Are you looking for an instrument that will assist you in testing how heavy, sticky or semi-fluid a substance is?

You might have heard about the viscosity tester but the information was not sufficient to convince you.

Well, worry no more as you are about to get the best of the details about this pharmaceutical instrument.

What is a Viscosity Tester?

A viscosity tester is a pharmaceutical instrument that you will use in testing the viscosity of certain pharmaceutical fluids.

You can also identify it as viscometer, rheometer or a viscosity meter in different avenues but it is one instrument.

It is an instrument that you will use in a pharmaceutical laboratory to measure the internal flow of fluid.

Bloom viscosity tester

To have a clear understanding of the viscosity tester, there are a few terms that you will need to know. Some of the terms include:

i. Viscosity which is a fluid property opposing relative motion between surfaces of the fluid moving at different speeds. It is the friction existing between the molecules of different fluids. When a fluid flows through a tube, the molecules near the axis move faster than the molecules near the walls.

Viscosity

ii. Resistance is the measure of the amount of opposition that exists between the molecules of a fluid. Liquids with low internal resistance are less viscous while liquids with high internal resistance are highly viscous.

iii. Shear stress is the force causing parts or layers to slide upon one another in different directions. It is a common phenomenon that is present in the flow of different types of fluids.

iv. Tensile stress exists in a fluid in a metastable stable state only in the presence of an energy barrier. It is the type of stress that does not exist in fluids due to particular reasons but it does.

v. Kinematic viscosity is a measure of inherent resistance in the flow of a fluid without the assistance of an external force. In this case, the only force in action is gravity and it will allow the fluid to move as you measure the viscosity. You can calculate it by dividing dynamic viscosity with the density of the fluid and it is independent of quantity.

vi. Dynamic viscosity of a fluid is the absolute viscosity of a fluid and is a measure of internal resistance to flow. It is the source of information on the kind of force that the fluid needs to flow at a particular rate.

The results that you will obtain from dynamic viscosity will assist you in getting the kinematic viscosity of a fluid.

You can, therefore, deduce and describe a viscosity meter as an instrument that measures the viscosity of a fluid.

It is the instrument that you will use to measure resistance to gradual deformation by tensile stress or shear stress.

For fluids it will correspond to the thickness of the fluid, for example, water has a lower viscosity than syrup.

You will use a viscosity tester in a laboratory but you might also use it practically in pharmaceutical factories.

Apart from that, you can also find it in different industrial environments for determining the viscosity of fluids.

It is important in the process of determining and controlling the quality of different fluids.

There are many types of viscosity testers that you can use in determining the thickness of a fluid.

They can either be portable, easy to hole in the hands, or bench top viscosity meter for real-time measurements.

Viscosity tester

The portable viscometers allow you to take a single point, simple measurements in the lab and also in the field.

Stationary or benchtop rheometer will allow you to work only in the laboratories as they are more complex.

You will use them to take more accurate and complex measurements of fluid samples.

They are very important in determining the viscosity of pharmaceuticals that require accuracy and precision in the manufacturing process.

Viscometer Appliance Standards

The appliance standard is the minimum standard of efficiency for different appliances that consumers use.

The standards help in the regulation of the quality of the different instruments from different manufacturers.

Appliance standards differ according to the standards set by different countries where you will be using the instrument.

Bloom viscosity tester

Pharmaceutical instrument manufacturers have to adhere to these standards to gain market access in different countries.

These standards help in protecting the consumer from fraudulent dealers who market substandard instruments.

The viscometer also complies with different appliance standards in accordance with the destination country.

The viscometer appliance standards include:

i. National standard (Food additive Gelatin) GB6783-94 which applies to gelatin, food additives, which you obtain through partial hydrolysis. It will involve hydrolysis of different raw materials from the skin, bone, scales, bones, tendons, and muscles.

ii. American codex/No.22/VSPXX which is the standard to refer to when dealing with products for the United States.

iii. Vocation standard (Gelatin for medicine) QB2354-98

iv. Vocation standard (Industrial gelatin) QB/T1995-94

v. Vocation standard (Bone gelatin) QB/T1996-94

vi. Vocation standard (Photographic gelatin) QB/t1997-94

The standards should guide the instrument manufacturer in making instruments of very high quality.

If the manufacturer does not comply, then the instrument will not be standard for use in pharmaceutical tests.

Features of the Viscosity Tester

The viscosity tester has very important features that enable it to perform various tasks.

The features will assist in doing the measurements and also displaying and remitting the information for analysis.

Viscosity tester machine

The main features of the viscosity tester include:

i. You can use it as a memory protection unit (MPU) to assist in controlling all the operations. The bloom viscometer works in the bloom mode and displays the viscosity data by light emitting diodes (LED).

ii. It is very accurate in high temperatures and allows even temperatures for the bat liquid.

iii. It calculates automatically the viscosity and time precise and capillary transducers.

iv. All the components in the instrument are of high quality and some of them are imports.

v. You can operate it easily by using keys and get the results of the measurements on the LED display.

vi. Direct and simple constructions make it have a pleasing and appealing outward appearance.

vii. Other features include low noise, slight shock, reliable performance, none-pollution, and durability.

There are special features that you need to look at when determining the type of viscometer to use.

These features will help in doing the right purchase as different viscometers will work for different applications.

Some of the factors to consider when determining the type of viscometer for use include:

i. The viscosity ranges of the fluid you intend to test or use. The viscosity ranged between high, medium or low viscosity for the fluids.

ii. Look at the shear rates or rotational speed that you will need for the different applications.

iii. Consider the size of the fluid sample that you intend to test.

iv. Look at the fluid and find out if there is a need for measuring the temperature before testing the viscosity.

v. You have to check on the nature of the fluid looking at whether it is Newtonian, dilatant, non-Newtonian or thixotropic.

You will go for a smaller viscometer if you intend to do small operations in the field and laboratories.

You should also consider the working budget so that you don’t acquire an instrument that you will not maintain.

These parameters will assist you in making the right choice for a viscosity tester.

Advantages of using the Viscosity Tester

Gathering data on the viscosity of a fluid will give the pharmaceutical technicians to know how the fluid will behave.

It gives an overview of the behavior of different pharmaceutical fluids when you take it to different environments.

Toothpaste can either be too thick to pump out or too light that is pumps out in excess.

Knowing how vicious a pharmaceutical fluid is will also assist in making the production and transportation design.

Viscosity tester display

Apart from having the details on the viscosity of a fluid, the viscosity tester has the following advantages:

i. Measures precise and accurate viscosities for a wide range of fluids. It includes the fluids that are outside the viscosity range and also those beyond specific temperature ranges.

ii. It has different varieties or designs that you can use in different environments. Some of them are small and portable and you can easily move them to different places.

iii. It also gives an allowance for using different varieties of capillary tubes on one viscometer.

iv. It uses digital systems making it easy to use and also transmit the right information for analysis.

v. It is flexible in taking different measurements depending on the different measuring values. This helps in making the process of analysis simpler and will save you a lot of time.

vi. Having a viscometer as part of the pharmaceutical instruments will reduce the cost of operations. You will save money that you could use in other experiments that the viscometer can easily perform.

vii. The instrument also improves the safety of doing pharmaceutical tests ensuring the safety of the technician. It will also help in the reduction of waste that may occur due to spillage of the testing samples.

viii. Apart from the ease of operations, it also provides better avenues for making adjustments. When you are operating the instruments, you will be able to adjust it according to the application.

ix. You can also link it to the computer that will help in the analysis of the results.

Types of Viscosity Testers

There are many types of viscometers that you can use in taking the viscosity measurements of fluids.

The difference in the type of instrument will range from different sizes, and also different applications.

You will choose the type of viscometer that you will need depending on the type of application.

1. Standard Laboratory Viscometer for Liquids

This type of viscometer for liquids has other names such as the U-tube viscometer, or the Ostwald viscometer.

The other version of the standard laboratory viscometer for liquids is the unbeloved viscometer.

It consists of a U tube standing vertically inside a water bath that for controlling the temperature.

One end of the tube is a narrow bore which you will identify as being the capillary.

Above the bore, you will see a bulb and there another bulb on the lower end of the other tube.

The two marks on the upper and lower part of the bulb above the capillary indicate the volume.

The time it will take for the test sample to pass through the two marks is a representation of kinematic viscosity.

U Tube Viscometer

Most of the viscometers have conversion factors or may have calibrations of fluids with certain properties.

In this type of viscometer, the main point will be on measuring time the liquid takes to pass through the two marks.

Multiplying the time and the viscometer factor will give you the results of the kinematic viscosity.

The viscometers in this category can either be reverse flow or direct flow.

Direct flow has the reservoir below the markings while reverse flow has the reservoir on top of the markings.

The direct and reverse classification is important because it will help in measuring every type of liquid.

There are instances when you will have to measure opaque liquids so it will come in handy in reading results.

It also gives the viscometer a better chance of displaying the results for immediate timing once it passes the mark.

2. Falling Sphere Viscometer

In this type of viscometer, the principle of stocks law will apply where the fluid is stationary in a glass tube.

You will then allow a sphere of the right density and size to fall through the liquid all the way to the bottom.

If you did the selection well, you will reach terminal velocity, which you can measure by looking at the time.

In this case, you will look at the time it will take for the liquid to pass the two marks of the tube.

In case you are testing the viscosity of opaque liquids, you can use electronic sensing to help in reading the results.

To get the viscosity of the sample fluid you are testing, you must have knowledge of the following properties:

i. Terminal velocity

ii. Density and size of the sphere

iii. The density of the sample liquid you are testing.

To improve the accuracy of the calculation, you will use a series of different balls with varying diameters.

In many cases, glycerin is the main fluid that you will use in the falling ball viscometer.

falling sphere viscometer

The falling ball viscometer is common in schools but you can also use it in different industrial and pharmaceutical applications.

The formula that you can use in determining the viscosity of different fluids id the Navier-Stokes equation.

The equation is F = 6πrnu where:

• F represents the force of friction
• r is a representation of the spherical radius
• n is a representation of the viscosity of the fluid
• u will represent the velocity of the particles.

The limiting factor, in this case, is the validity of the results that you will obtain from the sample test.

The sphere you will use in determining the viscosity of the fluid is the source of invalidation of the results.

Many people question how the roughness of the sphere affects the overall results.

There has, however, been a modification of this factor to eliminate the problems many people associate with the roughness of sphere.

The rolling ball viscometer comes as the replacement or modification of the falling sphere viscometer.

The rolling ball viscometer will time the ball that rolls down the slope in an immersion of the test fluid.

You can improve the model further by using a V plate that will increase the number of rotations at a particular distance.

This modification will allow for smaller devices that you will be able to move from one place to another.

3. Falling Ball Viscometer

This is the first viscometer in the whole world that was able to determine dynamic viscosity.

It is designed by Fritz Hoppler who came up with the idea and hence the name of the viscometer.

Apart from the falling ball Viscometer.

Fritz Hoppler was able to come up with other instruments such as the Ball Pressure Rheoviscometer or Consistometer.

It uses the Hoppler Principle in determining the viscosity of different test fluids.

This is a simple and precise method that determines the viscosity of Newtonian fluids.

It measures the time it will take for a ball to fall through a sample fluid under test by gravity.

The tube containing the sample fluid has to be in a particular angle as you allow the ball to fall through the liquid.

You will mount the tube on a pivot bearing which will allow the tube to rotate at an angle of 180 degrees.

The rotation at 180 degrees will give an allowance for the repeat test to occur immediately.

It is important to do the test three times as you record the time it takes for the ball to fall through the sample fluid.

You will then find the average of the time you record from the three experiments.

You will use the time value and convert it into a viscosity value using a formula.

There are two main models of the falling ball viscometer available and they include:

i. KF30 which complies to the DIN 53015 and is a tilt at an angle of 80 degrees.

ii. KF40 which allows tilts at angles of 50, 60, 70 and 80 degrees.

The main features of the instruments include:

i. It has a pivot bearing that allows for easy and quick rotation of the tube. This feature will also allow you to do as many repeat tests as necessary.

ii. It has a connection to a circulating bath that will allow you to control the temperature of the sample.

iii. It also has a set of balls that will allow you to do tests of different varieties of fluids.

iv. The instrument also has temperature probes.

v. It is an accurate instrument with a varying range between 0.5% to 2% depending on the ball.

You will use the falling ball viscometer in different industrial applications such as the pharmaceutical industry for quality control.

It is available in many academic institutions to assist in doing pharmaceutical research.

The straightforward time recording and ease of using the instrument ensure that you get meaningful and accurate results.

4. Oscillating Piston Viscometer

You can identify the oscillating piston viscometer with other names such as the electromagnetic viscometer or the EMV viscometer.

It is a product of the research at Cambridge viscometers and has a sensor that will assist in doing the tests.

The sensor consists of a piston that is magnetically influenced and a chamber for taking the measurements.

The oscillating piston viscometer will allow you to take measurements of different types of fluids.

It allows you to take measurements and control of transparent fluids, opaque fluids, and translucent fluids.

The function of the oscillating piston viscometer is fully automated thus eliminating any room for errors.

Oscillating Piston Viscometer

The electromagnetic piston will maintain a sample that is continuously fresh during the test.

You will also require a very small sample of the fluid for use.

In the long run, the instrument will allow you to determine accurate viscosity results using very small samples.

The instrument t will allow you to determine the results of both kinematic and dynamic viscosity of fluids.

You will introduce the fluid sample in the test chamber which also has absolute control of the temperatures.

The chamber is also the place where the oscillating piston resides thus most of the functions will occur in the chamber.

Electronics will drive the piston in oscillatory motion in the chamber with control of the magnetic field.

As the piston moves inside the test sample, it will impose shear stress in the chamber.

You will record the time it will take for the piston to rotate within the chamber for determination of viscosity.

This method will allow you to test the viscosity of small samples and of micro-samples in the laboratory.

It also allows for the measurement of viscosity at high pressure and temperature in industrial environments.

5. Vibrational Viscometer such as Quartz Viscometer

Vibrational viscometers will use a vibrating rod in measuring the viscosity of different fluid samples.

The principle lies with the different reactions or resistance of fluids to vibration depending on the viscosity of the fluids.

In this case, you will have to look at how fast the vibration degrades to determine the viscosity of the fluids.

Vibrational Viscometer

They are very sensitive and the parts of the instrument do not have to move whenever you are doing the tests.

This type of viscometer is important in the pharmaceutical industry where constant fluid viscosity should be on the record.

The viscometer has an electrochemical resonator that you will immerse in the fluid that you will need to test.

The resonator can either be a cantilever, tuning fork or oscillating beam.

The factors that will assist you in determining the viscosity will depend on:

i. The power you will need to keep the resonator in the oscillation mode at a particular frequency

ii. The time it will take for the fluid sample under test to decay after you stop the oscillation

iii. Observation of the difference in the different waveforms.

The advantages of using this type of viscometer include:

i. You can measure changing temperature and viscosity without replacements on the sensor plates.

ii. You can measure low viscosity of fluids accurately

iii. It is the solution to difficult viscosity measurements such as flowing and foaming.

iv. The instrument is very accurate and it remits results in a very short period.

v. It allows for a wide range of measurements and does not alter the texture of the sample fluid. This property allows you to use the instrument in determining the viscosity of Non-Newtonian fluids.

One of the main types of the vibrational viscometer is the quartz viscometer.

It has oscillating quartz that you will immerse in the liquid and observe the influence of the oscillating behavior.

The observation of the oscillating behavior will be the main determinant of the viscosity of the sample fluid.

Application of a high-frequency electrical field will lead to sensor movement and fluid shearing.

Shear stress within the process will cause disturbance of the electrical flow thus leading to a record on calibration.

Analyzing the calibration record will, therefore, allow you to get the viscosity of the test fluid.

6. Bubble Viscometer

This type of viscometer will help in the determination of the fluid kinematic viscosity in varnishes and resins.

The time it will take for a specific air bubble under observation to rise is directly proportionate to fluid viscosity.

In a case where the bubble rises faster, you will note that the fluid has a lower viscosity and vice versa.

Bubble viscometer

The method of using the bubble viscometer is very accurate but can also vary in the process.

The variation is a result of changing fluid buoyancy as the bubble also changes shape within the tube.

You should note that the difference will not cause any problems during calculation.

You can use it to get accurate data on kinematic viscosity using an alphabetical method of comparison.

The main features of the bubble viscometer include:

i. It comprises bubble viscometers and viscosity tubes that will act as fluid containers.

ii. It has a wide range of viscosity measuring kits. In a set, you are likely to get 4 different types of viscosity kits for doing the tests.

iii. It is a simple instrument that is user-friendly and easy to operate.

iv. The instrument is very accurate and precise and produces credible results.

v. It has an ergonomic design that is very reliable.

vi. It is durable and you can use it for a very long period.

7. Rectangular-slit Viscometer

The design of the rectangular-slit rheometer or viscometer consists of a slit channel in a rectangular cross-section.

You will then pump a sample of the test fluid at a flow rate that is constant through the slit channel.

Rectangular slit Viscometer

There are multiple pressure sensors that will detect and determine pressure drops in the system.

The slit rheometer or viscometer works on the principle that viscous liquids will be resistant to low.

As the viscous fluid flows through the rectangular slit rheometer, the pressure sensors will record low pressure.

This point you are able to use a formula to calculate viscosity using shear stress, and shear rate values.

The advantages of using the rectangular slit rheometer or viscometer are:

i. You will need to use very few microliters of the sample fluid for the test. It will help in reducing wastage of the sample fluid in doing the tests. It will also help in reducing the cost of expenditure in doing these tests.

ii. It also allows you to do tests of Newtonian and non-Newtonian fluids. It has a wide range of tests fluids that you can easily test.

iii. It allows very high shear rates with very minimal instabilities on the flow.

iv. It reduces and prevents the contamination and loss of the fluid sample through evaporation.

v. It renders very high levels of throughput as it has a simple design.

8. Rotational Viscometers

Rotational viscometers have two main parts where one will rotate like the other remains still.

The rotation of the cylinder inside the device will cause shear stress of the fluid allowing the fluid to flow.

The force that you will need to give a certain angular velocity will be the determinant of fluid viscosity.

Rotational Viscometer – Image source: Gardco

Some of the two main parts of the rotational viscometer have a separation due to the flow of the fluid.

The two parts can either be parallel plates, cone pate at low angles, concentric cylinders, or a spindle in a cylinder.

One part of the rotational viscometer will rotate as the other parts remain stationary.

Normally, the cone and plate model is the other type of rotational viscometer consisting of low angle cone above flat plates.

In this case, the cone or the plate can rotate as the other part remains still.

You can use the rotational viscometer to measure the viscosity of cosmetics such as lotions, and shampoos.

The advantages of using the rotational viscometer include:

i. You can use it to determine the viscosity of settling, opaque and non-Newtonian fluids.

ii. You can use it to characterize shear thinning and behavior of fluids that depend on time.

iii. You can adjust the speed of the parts that rotate very easily.

iv. You can link it to a computer to assist in measurements as they are semi-automatic.

Calculation of shear rate and shear stress factors

Viscometers and Rheometers work with angular velocity and torque.

Most of the time the values we get are of shear rates and shear stress and it is important to have a method for conversion.

In this case, you will need to convert the results from the instrument into the viscosity results that you need.

Every instrument that you will use in measuring viscosity will have a correspondent form factor.

The factor will assist in converting force to shear stress and angular velocity to shear rates.

You can identify the form factor of the shear rate as Ci and factor of shear rate as C2.

Shear stress = C1 multiplied by Torque

Shear rate = C2 multiplied by Angular Velocity

Viscosity = Shear stress divided by the shear rate

After determining the values of shear stress by multiplying C1 by the force.

You can as well determine shear rate by multiplying C2 by the angular velocity.

You will then determine the viscosity of the fluid by dividing shear stress by the shear rate.

9. Electromagnetically Spinning Sphere Viscometer

This electromagnetically spinning viscometer will measure the viscosity of fluid through observation of a rotating sphere under the power of electromagnetic interaction.

There are two magnets that are part of the rotor creating a rotating magnetic field.

EMS Viscometer – Photo courtesy: KEM

The sample that you will test and an aluminum sphere is inside a tube inside a chamber of controlled temperatures.

Normally, the tube is set in a position where the sphere inside the tube is within the range of the rotating magnetic field.

The resulting factors are the rotation of the sphere that is inside the test tube.

The velocity and speed of rotation of the sphere will depend on:

i. The magnitude or size of the magnetic field

ii. The rotational speed of the magnetic field

iii. The viscosity of the sample fluid that you will be testing

There is a video camera right below the set up that will record and monitor the motion of the sphere.

The force under the sphere is the same as the difference in the angular velocity of the sphere and the magnetic field.

The main characteristics distinguishing the EMS form other rotational viscometers are:

i. All the parts of the viscometer that is in direct contact with the sample fluid are inexpensive. Most of the technicians dispose of them as soon as they have the results they need.

ii. You will have to perform the measurements in a sample vessel that has a seal.

iii. The process of determining viscosity will require the use of very small quantities of the sample fluid.

10. Stabinger Viscometer

The external part of the Stabinger viscometer has a rotating tube with the sample liquid for test inside.

https://youtu.be/fI7MhIzWWPE

The tube is inside a cooper housing with temperatures that you can control easily.

Its hollow cylinder makes the internal part of the viscometer and is in the test fluid by centrifugal and hydraulic force.

The instrument provides very efficient and accurate results even though it involves a complex process.

Obviously, the results you will receive during this test will be determinants for getting the viscosity of the fluid using a formula.

The formula involves dividing dynamic viscosity using the density of the test fluid to get kinematic viscosity.

11. Miscellaneous Viscometer Types

There are other types of viscometers that use different types of materials and objects such as balls.

The viscometers that you can use in the characterization of non-Newtonian fluids are the plastometers or rheometers.

The other types of viscometers include:

i. The I.C.I “Oscar” viscometer

ii. Marsh Funnel Viscometer

iii. The flexible blade rheometer

How a Bloom Viscosity Tester Works

The bloom viscosity tester is one of the types of viscosity testers that are available in the market.

The principal of testing viscosity is the same but the method may vary depending on the type of viscometer.

Digital Viscometer – Photo courtesy: Doha Meter

In this case, we are going to have a look at how the bloom viscosity tester works.

The bloom viscosity tester measures the bloom viscosity of gelatin.

Normally the viscosity of different gelatin solutions depends on temperature, concentration, and the bloom value.

The method for determining viscosity involves measurement of efflux time roughly 100 ml of the test solution using a pipette.

It features an MPU which controls all the activities on the instrument while it works on the bloom mode.

Most of the results you will get from the tests you do with the bloom viscosity tester are on LED display.

It is very accurate in high-temperature operations as it has even temperatures of the bath liquid.

Back end of Viscometer

It also uses the precise and capillary photo-electric transducers as it calculates viscosity and time.

It has an auto timer, automatic alarm system, and automatic resting that will go off when the test is ready.

Apart from that, it has an automatic preset number, test hardness, preset of display of data in real time.

Alternatively, the above automatic properties, it can also perform automatic tests, diagnosis and an alarm to alert you.

The alarm will go off when the test is ready and you will be able to get the viscosity results on the LED display.

After setting up the whole system with the fluid sample for the test.

You can live it to automatically operate.

You will also set the time it might take for the instrument to take the right viscosity measurement.

Apart from that, the machine can do repeat examination of the fluid depending on the number of times set.

The data on every form of the result will be in store ready for analysis thus making it the most efficient instrument.
