Embodiment Construction

[0027] The overall scheme of the automatic liquid suction and liquid separation system for a single micro-sampler involved in the present invention is to realize the free combination of liquid channels and corresponding working modes from suction to distribution of liquids by switching the liquid suction and liquid separation electromagnetic selection valves. Under the control of the control system, the pre-set liquid suction and liquid distribution tasks are completed.

[0028] The single micro-sampler automatic liquid suction and liquid separation system involved in the present invention includes a cleaning liquid container (1), a liquid container to be distributed (2), a multi-channel liquid suction electromagnetic selection valve (3), a double-channel electromagnetic valve (4 ), liquid main channel (5), multi-channel liquid separation electromagnetic selection valve (6), micro sampler (7), sampler drive arm (8), precision stepper motor (9), waste liquid container (10 ), th...

Abstract

An automatic liquid adsorption and distribution system of a single microsyringe is characterized by complicated functions of freely combing liquid adsorption channels and liquid distribution channels, automatically adsorbing a plurality of liquids by the single microsyringe, and distributing the liquids to different containers. The automatic liquid adsorption and distribution system includes a cleaning liquid container, to-be-distributed liquid containers, a multi-channel liquid absorption electromagnetic selector valve, a double-channel electromagnetic valve, a liquid master channel, a multi-channel liquid distribution electromagnetic selector valve, the microsyringe, a microsyringe drive arm, a precise stepping motor, a waste liquid container, distributed liquid containers, a controller and control lines. The automatic liquid adsorption and distribution system can switch the electromagnetic valve to select the required liquid channel, and realize the liquid adsorption and distribution function through the up and down movement of the piston of the microsyringe, and can be widely applied to chemistry, biology and other analysis and test experiments.

Description

technical field [0001] The invention relates to an automatic liquid suction and liquid distribution system which can use a single micro-sampler to absorb multiple liquids and distribute them to multiple containers. Background technique [0002] In chemical and biological analysis and testing experiments, high-precision micro-liquid absorption and distribution are often required. In addition to the traditional manual use of pipettes and pipette guns, some high-end customers also use liquid distribution workstations. The so-called liquid distribution workstation (also known as pipetting system, sample system, etc.) is a processing system that automatically pipettes liquid with a manipulator. The manipulator can perform precise pipetting from left to right or in the opposite direction, and the pipetting head sucks and distributes samples through the XYZ axis. . Due to the mechanical arm, this method has complex structure, high cost and complicated maintenance, so many customer...
