可编程膜片钳实验自动换液器的研制

The development of an automatic device for changing experiment liquid in the patch clamp experiment

本文介绍利用８０３１单片机控制步进电机及微型电磁阀而实现的一套自动变换药液装置。该装置可由用户对药液的变换过程自行编程或修改，编程方案具有断电保存功能。作为自动化细胞电生理膜片钳实验的一个辅助设备，该装置提高了实验的效率。

The article reports a kind of automatic device using 8031 single chip microcomputer for the control of a stepping motor and small electromagnetic valves.All liquid change procedures are progra mmable and adaptable,with hold function under power off condition. As an ancillary device for the petch clamp experiment on cell electrophysiology,it improves the efficacy of the experiment.
