The tap density tester is ideal for measuring the tapped density of powders, granules, pellets, flakes and other substances. The instrument is suitable for 100ml and 250ml volumes and supports USP 1 (300 taps per min) and USP 2 (250 taps per min), ASTM test methods and user defined tests. Friction-free bearings ensure a free drop of the cylinder from the required height. At the end of the test, results like tapped density, compressibility index and hausner ratio are calculated and displayed.
