    • Device for testing the potency of a biological control reagent, as in antibiotic susceptibility testing, especially the determination of minimum inhibitory concentration, comprising a strip of a plurality of interconnected plastic cups having a capacity of about 0.3 ml. each. All but two of the cups contain a range of amounts of the control reagent in an essentially dry state which will provide a predetermined range of concentrations when the reagent is redispersed. Contamination of the dry reagent in the cups is prevented by an adherent plastic film or aluminum foil across the openings of the cups. In use, the adherent film or foil is removed, the dry reagent is redispersed to form the required range of concentrations, and all of the cups except one are inoculated with the biological material against which the potency of the control reagent is to be tested. The last cup contains the dispersion medium but not the control reagent nor inoculum, and provides a sterility control. The second last cup contains the dispersion medium and the inoculum, and serves as a growth control. The strip of cups is then resealed, incubated, and the test results are read.
    • 用于测试生物控制试剂的效力的装置,如在抗生素敏感性试验中,特别是最小抑制浓度的测定,其包含容量为约0.3ml的多个相互连接的塑料杯条。 每。 除了两个杯子之外,除了两个杯子之外还包含一定量的基本干燥状态的对照试剂,当试剂再分散时,其将提供预定范围的浓度。 通过在杯子的开口上的粘附塑料膜或铝箔来防止杯子中干试剂的污染。 在使用中,去除粘附膜或箔,干燥的试剂再分散以形成所需的浓度范围,除了一种以外的所有杯子都接种用于测试对照试剂的效力的生物材料。 最后一杯含有分散介质,但不含对照试剂和接种物,并提供无菌控制。 第二杯含有分散介质和接种物,并用作生长控制。 然后将杯条重新密封,孵育,并读取测试结果。
