The widespread use of powders in the pharmaceutical industry has led to a proliferation of test methods for measuring powder flow and density.
The new harmonised chapters in the Pharmacopoeias on Powder Flow (USP Chapter <1174> and Ph.Eur. 2.9.36) list four well defined methods for powder testing aimed at trying to bring about some degree of standardisation within the test methodology:
- Flow through an orifice
- Angle of Repose
- Shear Cell
- Compressibility Index and Hausner Ratio
The new Flowability Tester BEP2 provides a range of options for testing pharmaceutical powders including three of the four methods quoted in the Pharmacopoeias – flow through an orifice, angle of repose and shear cell – in a single, cost effective unit.
For compressibility index and Hausner ratio testing, we offer a series of tapped density testers and the bulk density tester (Scott Volumeter), detailed monographs for which feature in USP Chapter <616> and Ph.Eur. Chapter 2.9.15.
