Tap Density Testers are microprocessor-controlled. This apparatus offers a simple and standard means of measuring the tapped density of powders, granules and pellets. It supports both USP-I and USP-II methods of testing, but allows only one test to be performed at a time. The test may also be performed as per ASTM standards using the optional adapter for cylinder holders. It has two different cylinder holders with snap-lock mechanism that are designed to hold the 100ml and 200ml cylinders. They have unique rotating & tapping motion for even packed surface and have acoustic cabinet to minimize noise levels.
