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.
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 use 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.
