    • In an automatic chemical testing apparatus, means are provided for dispensing aliquots of a sample to reaction containers. A carriage means housing a self-priming hydraulic circuit mounted for motion on a support arm housing drive means. During an operating cycle, control means operate the drive means to position a conduit communicating with the hydraulic circuit over a sample source and aspirate an amount of the serum into the hydraulic circuit. The carriage means is then moved, preferably at uniform rate over a row and dispensing means are pulsed to dispense samples into individual reaction containers while the carriage means is moving. The carriage means is then returned to its starting position.
    • 在自动化学测试装置中,提供用于将样品的等分试样分配到反应容器的装置。 托架装置,用于容纳安装在运动中的自吸液压回路,该支撑臂容纳驱动装置。 在操作循环期间,控制装置操作驱动装置以将与液压回路连通的导管定位在样品源上,并将一定量的血清吸入液压回路中。 然后,滑架装置优选以均匀的速率在一排上移动,并且分配装置被脉冲以在支架装置移动的同时将样品分配到各个反应容器中。 然后,托架装置返回到其起始位置。
