Measure the Tapped Density of Powders, Granules and Similar Products

For Immediate Release: Tapped Density Testers measure the tapped density of powders, granules and similar products. This technique is particularly useful in powder flowability studies and also in determining the amount of settlement during transit in order to optimize pack sizes e.g. washing powders. Tapped density is achieved by mechanically tapping a measuring cylinder (i.e. raising the cylinder and allowing it to drop the specified distance of 3 +/- 0.2 mm under its own weight) containing the sample under test.

Two versions of the tester (JV 1000 and JV 2000) are available dependent on the number of test stations required (one or two). Both versions utilize 250mL measuring cylinders as standard; however, 100 mL cylinders (and smaller) together with appropriate platforms are also available if required. Both of the instruments are equipped with membrane keypads for setting the number of strokes or time and an LCD screen to set the appropriate parameters and monitor the progress of the test.

*In accordance with Methods 1 and 2 of USP Chapter and European Pharmacopoeia Chapter 2.9.34.
*Item Nos. WG-490010, WG-490020

Operation:
The mode of operation is identical on both models. Weigh out a predetermined amount of the sample, say 100 g +/- 0.1%, place it in the graduated cylinder provided and note the unsettled volume. Secure the graduated cylinder to the test platform of the tester using the bayonet fitting provided for this purpose. Unless otherwise specified, set the number of taps via the membrane keypad on the front of the instrument to 500 and operate the device making a note of the resulting tapped volume. Repeat this operation for a further 750 taps noting the volume once again. Continue repeating the test in increments of 1250 taps until the difference in tapped volume is less than 2%. Note the final reading.
