RECORDING POWDER FLOW METERS AND THEIR USE IN PHARMACEUTICAL TECHNOLOGY

Recording Powder Flowmeters (RPF) have received relatively little attention in the literature. This paper reports on a modified RPF which utilizes a Mettler PR-1200 electronic balance rather than the traditional specifically fabricated flowmeter. The versatility of this modification is discussed as a cost effective modification. This modification provides for the use of RPF's in many areas of pharmaceutical technology. The reproducibility of RPF data with its sensitivity to processing and formulation variables has been investigated. Suggestions for the application of RPF data in quality control, preformulation and other research areas of pharmaceutical manufacturing are discussed. © 1979 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
