    • A diffusion test apparatus (2), used to test diffusion of a drug within a vehicle through a test membrane (8), includes a receiver assembly (6) and a donor assembly (4) secured to one another. The receiver assembly includes a number of open-top receiver receptacles (26) arranged in a chosen pattern along its face (12). Similarly, the donor assembly includes a number of open-top donor receptacles (38) arranged along its face (10) in a mirror image of the chosen pattern. The test membrane is captured between the receiver and donor faces. The drug diffuses through the test membrane and into the receiver liquid (53) during an incubation period (62). Samples (66) of the receiver liquid are preferably automatically transferred to a conventional microtiter plate (70) using a programmed liquid transfer system for assay by a scintillation counter (76).
    • 用于通过测试膜(8)测试车辆内的药物扩散的扩散测试装置(2)包括彼此固定的接收器组件(6)和供体组件(4)。 接收器组件包括沿着其表面(12)以选定的图案布置的多个敞开式接收器插座(26)。 类似地,施主组件包括沿所选择的图案的镜像沿着其面(10)布置的多个开顶施主插座(38)。 测试膜被捕获在接收器和供体面之间。 在潜伏期(62)期间,药物通过测试膜扩散入接收液体(53)。 接收液体的样品(66)优选使用编程的液体转移系统自动转移到常规微量滴定板(70),以便通过闪烁计数器(76)进行测定。
