Tap Density Tester
This test measures increased bulk density attained after mechanically tapping a graduated measuring cylinder or vessel containing a powder sample. After observing the initial powder volume or weight, the measuring cylinder or vessel is mechanically tapped, and the volume or weight readings are taken until little further volume or weight change is observed
- Designed to meet current USP and ASTM Specifications fortap density testing.
- The unique simultaneous tapping and rotating motion assures that the material is evenly packed.
- Calculates test results – Tapped Density, CompressibilityIndex, Hausner Ratio, and Bulk Density.
- Two cylinder holders will hold 100 mL and 250 mL cylinders.
- Balance interface for sample weight transfer.
The Tap Density Tester is advance microcontroller based with user friendly software in dialog mode. The Alpha-Numeric splash proof keyboard allows entries such as sample name, sample number or ID number for data authentication. The report printout complies with GLP requirements and a built-in Real Time Clock provides date, time display, and authenticity of the printout.
