Digital Friability Test Apparatus is a precision instrument suitable for measuring obression strength of tablets. The unit is equipped with two transparent acrylic drums which rotate at a speed of 25 ± 1 RPM. Each of the two acrylic drums are provided with an arm which carries the tablets along with it up to a predetermined height and allows them to fall from that specified height, while the drums are rotating, It is fitted with a digital revolution counter showing the current number of revolutions for the test. A thumb wheel switch is used to set the desired number of rotations. Provision is made to remove the lid of the acrylic drum by unscrewing just one knob. This is available in 1 drum and 2 drum assemblies.

Microprocessor Friability Apparatus, Model 1902 measures the tendency of a tablet to chip or breakdown to pieces when held under mechanical stresses. Instrument uses the latest microcontroller technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility.

System is equipped with 4 line alphanumeric LCD display with backlit and 16 number of soft touch membrane type keys.

The friability tester can be operated using only one or two drums. The rotational speed of drums can be set at different speeds (20-60 RPM). The samples can be loaded conveniently without removing the drums and after the test completion the samples are automatically unloaded to the collection tray.

To eliminate the manual input of weight of samples the facility of connecting a weighing scale is also available. When weighing scale is connected the weight of samples is automatically recorded to the instrument from the weighing balance.

The test can be performed in two different modes Time or Count mode. The instrument stores the test parameters, readings and results simultaneously in the memory which are retained even after the power is switched OFF. Provision has also been made for attachment of a printer so as to provide hard-copy printouts of test data, including the time, date and calculated results.
