HMKFlow 329 Powder Flowability Angle Of Repose Tester P/N 32998 picture is subject to latest catalog upon inquiry and quotation
HMKFlow 329 is an apparatus of angle of repose usp 1174 used to measure the angle of repose of pharmaceutical powders. Powder angle of repose is part of powder flow test. HMKFlow 329 conforms to US Pharmacopoeia Chapter USP 1174 and European Pharmacopoeia Chapter EP 2.9.36. It also meets ISO 4324and agricultural fertilizers(ISO 8398). The angle of repo
se is the angle of the conical pile produced when a granular sample is poured onto a horizontal surface (test platform). HMKFlow 329 is supplied with free Windows software to obtain the test results in a second.
HMKFlow 329 consists of a stand, funnel, stirrer, test platform and a digital height gage, having a range of 0-300 mm and an accuracy of 0.05 mm.
Pour sample into the funnel and stir the sample if necessary, the powder produce a cone on the test platform and use a digital gage measure the height of the pile. The tangent of the angle of repose (in degrees) can be determined by reading off the height of the powder cone in mm from the digital display of the height gage and dividing it by 50.
Table EUROPEAN PHARMACOPOEIA 2.9.36-1. – Flow properties and corresponding angles of repose
• 25-30° Angle of repose corresponds to Excellent flow property
• 31-35° Angle of repose corresponds to Good flow property
• 36-40° Angle of repose corresponds to Fair – aid not needed flow property
• 41-45° Angle of repose corresponds to Passable – may hang up flow property
• 46-55° Angle of repose corresponds to Poor – must agitate, vibrate flow property
• 56-65° Angle of repose corresponds to Very poor flow property
• >66° Angle of repose corresponds to Very, very poor flow property
With solely developped calculation and conclusion software, operator easily got results of powder flowability.
