The TAP-2S tap density tester is designed for powder/granule tapping or bulk density tests in compliance with USP, BP, and EP. TAP-2S is designed for USP Methods I and II, and comes complete with interchangeable 100 ml and 250 ml glass cylinders and holders. When in motion, the cylinder simultaneously taps and rotates, insuring that the material being tested is packed evenly throughout the cylinder and leveled with the cylinder surface for direct reading.
In operation, the user loads the powder or granules into a cylinder and places it on the platform. The test time or number of taps is easily entered using the instrument’s keypad. The run parameters are clearly shown on the LED display in real time.
The cylinders are driven by a silent step motor that is fixed at 250 (USP Method II) or 300 (USP Method I) strokes per minute. There are a few options with this product. A unit can be purchased with two cylinder holders for USP Method I and run simultanesouly. A unit may also be purchased with two cylinder holders for USP Method II. A third option is a unit that has both USP Method I and II, but individual tests must be done.
