The TAP-2SP tap density tester is designed for powder/granule tapping or bulk density tests in compliance with USP, BP, and EP. The 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, each 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 printer reports the test data at the end of each tap cycle.
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. Units may be purchased to perform either USP Method I or USP Method II on both platforms or a combination of the two methods on a single unit.
In order to meet the validation, Logan TAP-2SP provides 4 certifications: The 100 ml glass cylinder and 250 ml cylinder, Method I holder and Method II holder.
