Problems solved by technology

[0002] In the current biological experiment and biological detection process, when the liquid samples required in the process are added, they are all operated by a pipette or a pipette gun, which is easy to cause harm to laboratory equipment or experimental operators during the operation. Contamination and inefficiency when using manual pipettes or pipettes
When adding samples, it is impossible to realize the micro-precision control of reagents, that is, the accuracy of adding samples is not high

Abstract

The invention discloses a sample adding device applied to a liquid biological reaction system and a control method, an X-axis moving component of the sample adding device is installed above a whole rack, a Z-axis moving component is arranged on the X-axis moving component, a sample adding component is arranged on the X-axis moving component, a Y-axis moving component is arranged on the whole rack, a tray component is installed on the Y-axis moving component, an inlet of a liquid circuit drive device is connected with a liquid storage device, a bubble sensor is installed on a pipeline, an outlet of the liquid circuit drive device is connected with an inlet of the sample adding component, and the X-axis moving component, the Z-axis moving component, the Y-axis moving component, the liquid circuit drive device and the bubble sensor are all connected with a PLC. The sample adding speed is greatly accelerated, the pollution is reduced in the process of adding a sample, and meanwhile, the sample can be added to eight biological reaction systems at the same time while the sample is added to the liquid biological reaction system.

Description

technical field [0001] The invention relates to the technical field of an automatic sampling device, in particular to a sampling device and a control method applied to a liquid biological reaction system. Background technique [0002] In the current biological experiment and biological detection process, when the liquid samples required in the process are added, they are all operated by pipettes or pipette guns, which is easy to cause harm to laboratory equipment or experimental operators during the operation. Contamination and inefficiency when using manual pipettes or pipettes. When adding samples, it is impossible to realize the micro-precision control of reagents, that is, the accuracy of adding samples is not high. [0003] The liquid biological reaction system is a container for micro reagent reaction, and the reagent is added to the reaction system through the sample port. Contents of the invention [0004] The present invention mainly improves on the shortcomings...
