PT-TD300 Tapped Density Tester

Tapped Density Tester

Tapped Density Testing

The PT-TD300 instrument measures the tapped and bulk or apparent density of powders, granules and blends according to USP <616>, EP <2.9.34-3>, ASTM and ISO testing standards. Tapped density is achieved by mechanically tapping a measuring cylinder (i.e. raising the cylinder and allowing it to drop a specified distance under its own weight) containing the sample under test. The tapped density in grams per mL can be calculated by dividing the sample weight by the final tapped volume. The PTTD has both 300 taps per min and 250 taps per minute stations. The 300 tap/min drops at a height of 14 mm whereas the 250 tap/min station drops at 3mm. The weight of the platform and cylinders are compliant as indicated by USP, ASTM and ISO.

The PT-TD300 comes with both 250 ml and 100 ml cylinders and platforms. Optional cylinders include 50, 25 and 10ml. The unit automatically detects in which position the cylinder dish is placed and adjusts the speed and tapping height accordingly. It is equipped with a user friendly LCD display. Methods for USP and EP are pre-programmed for a quick test start. It is also possible to create and store customized test methods. The operator inputs the initial sample weight and volume as well as the final tapped volumes. The unit will automatically calculate the initial density, the tapped density, Hausner flowability ratio and Carr compressibility index after each test and documents the results via the integrated protocol printer. The PT-TD300 can be also be connected to a serial or LAN prot for data export/PC connection. An optional Noise Reduction cabinet is also availble.
