What is table friability tester?
Friability is the chipping or crumbling of a tablet due to compression during packaging or transit.
High Quality Us Low Quality Tablets
Tablet friability testing is carried out in pharmaceutical company laboratories.
A friability tester is a piece of equipment mainly used to determine how long tablets can last during transportation without having to break.
When this equipment is used, it raises a flag on quality issues of uncoated tablets.
Tablet Friability Tester
Tablet friability can be caused by several factors. Causes can include poor tablet design like:
- Sharp edges
- Low moisture content
- Insufficient binders.
When there is a weight loss on sample tablets of more than 1%, then we can say there is a problem with production quality.
In this case, the pharmaceutical company must find out the reason behind it.
There’s a possibility that the shape of the tablet is the cause so that the design must be changed.
Sometimes it could be due to low moisture content in the tablets.
The test process involves dropping some tablets into a drum.
This is done using a rotating wheel with a baffle over a specified fixed time frame.
After that, inspection is done to find the broken tablets.
An example of a tablet friability tester is this diagram below.
Tablet Friability Tester Equipment
Why is Tablet Friability Testing Important?
Some of the main reasons why you need a tablet friability tester include:
Tablets Manufacturing and Quality Control
- Helps to determine the resistance of uncoated tablets to abrasion and shock during manufacturing, packing, and shipping.
- Provides pharmaceutical companies with an opportunity to carry out research. Knowledge about the cause of breakage of the tablets during testing could reduce company loses.
- Controls the stability of uncoated tablets in pharmaceutical industries, hospitals, and drug testing institutions.
- Provides data for sugar-coated tablets which is reliable.
- Protects the consumer right. Some tablets can lose 1% or less weight, and this is generally acceptable.
But if the sample tested has lost more than 1%, that particular batch of drugs is not recommended for use.

In 2011, there was a 46thpharmacopeia discussion group meeting hosted by WHO.
The attendants of this meeting were the United States, Japan, and European experts.
They harmonize specifications for pharmaceutical preparations.
For example, they agreed that a tablet friability tester should have the following specifications:
- A drum with an internal diameter of between 283 and 291 mm and a depth of between 36 and 40 mm.
- It should be made from a synthetic polymer which has a polished internal surface.
- The drum should be removable from one side.
- Inside that drum, there should be a projection that is curved which has an inside radius of between 75.5 and 85.5 mm. This should extend from the middle of the drum to the outer wall.
- It should be connected to a horizontal axis of a device that rotates at a speed of 25 1 rpm.
- Tablets weighing more than 650 mg are put in samples of 10, dusted and weighed.
- Cleaved, broken and cracked tablets in a sample show that the sample has failed the test. The target value is always 1%. If the results of a test are less than the target value, the test should be repeated three times and the average calculated.
- If the shape or size of a tablet is causing Tambling to be irregular, the drum can be tilted at 10º.
As you can see, there is a clear procedure on how to assess the quality of tablets.

vii. Those with many drums have automatic discharge and tablet collector tray where tasted samples are discharged into.
viii. Multi-drum tablet friability testers like a triple, four and six drums have printers and a connection for USB.
Tablet Friability Tester Calibration Process
As a rule of thumb, before using any pharmaceutical instruments, ensure it can record or display accurate results.
To do this, it measurements must conform to certain set standards.
That’s exactly what you’re going to learn here.
What is Tablet Friability Tester Calibration?
It is configuring the tester to provide sample results within an acceptable range.
It eliminates or even minimizes factors that may cause inaccuracy in measurements.
Normally, it is a primary process of maintaining the instrument.
It tests samples of values of a calibrator.
Friability Test Apparatus
Tablet friability tester calibration involves two sub-processes which are discussed below.
Number of rotation in 1, 2 and 4 minutes calibration
To calibrate the instrument in a rotation of 1, 2 or 4 minutes, on the function key, set the time mode.
If you want it to run for 1 minute, select 1 minute mode.
You can then start the instrument and see the revolution numbers in a minute.
Repeat the same process for 2 and 4 minutes and after that, record the results.
All these three tests must be performed three times to ensure reliability and accuracy.
Below is an example of an acceptable number of rotations in 1, 2, and 4 minutes.
- Number of rotations acceptable for 1 minute are Between 24 to 26 rotations.
- Number of rotations acceptable for 2 minutes are Between 48 to 52 rotations.
- Number of rotations acceptable for 4 minutes are Between 96 to 104 rotations.
Calibration for 25, 50 and 100 rotations for time
Here, you calibrate the equipment to rotate 25, 50 and 100 rotations and select the count mode.
You can then start the apparatus and use a stopwatch to stop at 25, 50 and 100 rotations.
This will help you determine the time each set of rotations takes.
Upon completion of each three calibrations, record all the results.
Below is an example of an acceptable time in minutes for 25, 50 and 100 rotations.
- It is acceptable to have 25 rotations in a time duration of between 0: 57 00 to1:03 00 minutes
- For 50 rotations, the time duration can be between 1: 54 00 to2:06 00 minutes
- When it comes to 100 rotations, the durations can range between 3: 48 00 to4:12 00 minutes.
