    • An apparatus for testing several physical properties of pharmaceutical powders, which apparatus includes a frame having a ram linearly movably supported thereon and driven from a microstepping rotary drive motor. The ram, through a first load cell, cooperates with a selected one of two different tablet supporting head assemblies which removably mount of the frame for respectively testing tablet hardness and tensile strength. The frame also mounts a powder flow test arrangement which includes a bed stationarily supported on the frame for receiving a layer of powder, and a sled which rests on the powder layer and is freely horizontal movable relative to the bed. The sled is coupled through a generally horizontal tension member to a second load cell which is mounted on the ram independently of the first load cell.
    • 一种用于测试药物粉末的几种物理性能的装置,该装置包括具有线性可移动地支撑在其上并由微步旋转驱动马达驱动的压头的框架。 压头通过第一测力传感器与两个不同的片剂支撑头组件中的一个配合,该组件可拆卸地安装框架以分别测试片剂的硬度和拉伸强度。 该框架还安装了粉末流动测试装置,其包括固定地支撑在框架上用于接收粉末层的床,以及搁置在粉末层上并可相对于床自由水平移动的滑雪板。 滑板通过大致水平的张力构件联接到独立于第一测力传感器而安装在压头上的第二测力传感器。
