    • A flow assessment apparatus (10) is provided for quantitatively assessing the flow properties of particulate material, such as pharmaceutical formulations and constituent powders. The apparatus (10) includes a vibratory feed device (12) having an inclined dispensing member (16). Particulate material is induced to flow along the inclined member (16) onto a watch glass (18) positioned on a top pan balance (20). The mass of material dispensed onto the watch glass (18) is recorded over a given time period, for example a set time period of 1 minute, or a visually assessed time period where it is deemed that sufficient material has been dispensed. The mass and time data is used to calculate a value representative of a relative flow property of the material, which can be used in the development of pharmaceutical formulations.
    • 提供流量评估装置(10),用于定量评估颗粒材料(例如药物制剂和组成粉末)的流动性质。 装置(10)包括具有倾斜分配构件(16)的振动进给装置(12)。 诱导颗粒材料沿着倾斜构件(16)流动到位于顶部平衡盘(20)上的手表玻璃(18)上。 分配到表玻璃(18)上的材料的质量在给定的时间段内记录,例如设定的时间段为1分钟,或视觉评估的时间段,其中认为已经分配了足够的材料。 质量和时间数据用于计算代表材料的相对流动性质的值,其可用于开发药物制剂。
