Pharmaceutical Instruments: The Ultimate Guide for Importers
Pharmaceutical instruments play a critical role in the medicine manufacturing process.
For instance, you must know the number of excipients, active ingredients, mole, humidity content, etc.
In fact, some ingredients are determined in small quantities such as milli (m), micro (µ), nano (n) or pico (p).
But, how do you achieve these?
You need high quality, accurate, and reliable pharmaceutical instruments.
That’s exactly what you’re going to learn here – let’s dive right in.
What are Pharmaceutical Instruments?
As a medical student, pharmacist, or anybody who has an interest in pharmaceutical instruments, it is important to know the definition.
To get a clear understanding, I am going to break the topic into two parts and explain them differently.
It is because many of the people who describe pharmaceutical instruments tend to confuse them and include pharmaceutical machines.
Pharmaceuticals are substances that you will use in diagnosing, treating, and preventing diseases that occur in human beings.
Doctors prescribe the pharmaceuticals for correcting, restoring and modifying the normal functions of the organs in the body.
They are the most significant components of both traditional and modern medicine for safe, effective and rational use.
Instruments, on the other hand, are devices, implements, gadgets, apparatus or tools that human beings use for precision works.
These devices communicate, detect, denote, measure, indicate, record, observe, and signals quantities and manipulate or controls other devices.
And, by the way, this is where some professions like pharmaceutical analysis come in hand.
You can have a look at this:
Many people tend to confuse machines and instruments and it is important to get a clear difference between them.
Pharmaceutical instruments are, therefore, devices that you can use to determine certain rational factors of the drugs and medicines.
It encompasses a great variety of equipment and products that you will find in the medical laboratories.
Every instrument will play a unique role in determining the variations in quality and quantity in the pharmaceutical industry.
Pharmaceutical instruments should have the highest mode of reliability, precision to come up with the best quality of drugs.
Drugs are the best option for fighting complications in the organs of the human body.
It is the reason why you have to use instruments with the highest precision as it will a life saver.
Uses of Pharmaceutical Instruments
You can use pharmaceutical instruments in many applications in the manufacture of pharmaceuticals such as drugs and medicines.
They are the instruments that you will employ in measuring different quantities and quality of pharmaceutical substances.
The most common uses of the pharmaceutical instruments are as follows.
1. Pharmaceutical Analysis
This is the process which involves different processes such as determination, identification, purification, and quantitation.
You can use pharmaceutical analysis instruments for separating contents from mixtures and determining the compound structure.
Basing the process on the type of determination you will go through qualitative and quantitative analysis.
Qualitative analysis of pharmaceuticals is the method of identifying the chemical compounds in the pharmaceuticals.
Quantitative analysis involves the process of determining the number of samples available in a particular combination.
They will help you determine the right combination factors to include in making the drugs you want.
Pharmaceutical analysis and testing instruments include many things such as reciprocating cylinders.
You can use the reciprocating cylinders to perform the following:
- Study the dissolution of the product with a release extension.
- Test the solubility of the pharmaceuticals by measuring the solubility of the solid drugs in different liquids.
The different types of pharmaceutical instruments for analysis will help in reducing validation timeliness and save the industry some money.
Just in case you have an interest in this subject, here is a good book for you: Pharmaceutical Analysis (A Text Book for Pharmacy Students and Pharmaceutical Chemist.)

4) Tablet Hardness Tester
Tablet hardness testing is a technique for testing structural integrity and breaking point of a tablet in the pharmaceutical industry.
The test of the tablet is under different conditions such as storage, handling before use and transportation.
You might confuse it with friability testing but they are very diverse.
The shape of the tablet will determine the breaking point of the tablet.
You can use two main methods to test the breaking point of the tablet or the hardness of the tablet.
The main processes are the three-point bends testing and compression testing.
Compression testing involves squeezing the tablet by two jaws after aligning it in a repeatable manner.
Tablet Hardness Tester
The machine squeezes on the tablet at different strengths and when it breaks, there is a record on the sliding scale.
The technician will read the record on the sliding scale and record it for further tests.
The most common hardness testers available in the market include:

Technicians confine this tendency to surfaces and tablets that do not have coats when handling or storing the tablets.
Tablet Friability Tester
Many factors can lead to friability of the tablet including the design, insufficient binder or moisture content among others.
Tablets should be strong enough so that they do not break in the storage containers.
They should also be friable enough so that they can easily disintegrate in the intestinal tract.
The friability tester determines the resistance of tablets without coats to shock and abrasion during manufacture, storage, and transport operations.
The design of the instrument does not change even though the ease of usage and reliability is improving rapidly.
The process of friability involves dropping the tablet repeatedly over a particular period in a rotating drum.
