摘要：A flow assessment apparatus 10 is provided for quantitatively assessing theflow properties of particulate material, such as pharmaceutical formulations andconstituent powders. The apparatus 10 includes a vibratory feed device 12 having aninclined dispensing member 16. Particulate material is induced to flow along the inclinedmember 16 onto a watch glass 18 positioned on a top pan balance 20. The mass ofmaterial dispensed onto the watch glass 18 is recorded over a given time period, forexample a set time period of 1 minute, or a visually assessed time period where it isdeemed that sufficient material has been dispensed. The mass and time data is used tocalculate a value representative of a relative flow property of the material, which can beused in the development of pharmaceutical formulations.
