Description

Technical Field

[0001] The utility model relates to the technical field of microbial solution processing, in particular to a liquid transfer mechanism and a processing system for microbial solution detection. Background Art

[0002] In the actual operation of microbiological solution testing, it is often necessary to sterile filter the microbial solution to obtain pure microbial samples, or remove microorganisms for certain chemical and physical tests. Traditional filtration methods usually rely on manual operations, which are not only time-consuming and laborious, but also prone to cross-contamination and sample contamination, affecting the accuracy of the test results. Manual operation can no longer meet the current needs of biochemical testing. It has become an inevitable trend to realize intelligent operation of part or all of the operation process.

[0003] Although there are pipetting devices that can support automated pipetting, their principle is usually to draw samples from the mother liquid, move them to a designated position and then release them to complete a single pipetting action. Repeating the above actions multiple times can complete the entire sample liquid pipetting process. In the process of microbial solution detection, it is necessary not only to extract and release the sample mother liquid, but also to extract the sample reaction liquid and release it into the sample bottle for detection after the sample mother liquid is mixed with the reaction substrate and subjected to centrifugal vortex oscillation. Before releasing the sample reaction liquid, it is also necessary to apply a filter membrane and other operations. Extracting the sample mother liquid and the sample reaction liquid also requires gun tips of different specifications. It is difficult for a conventional single pipetting mechanism to complete the automated operation process of the microbial solution.

[0004] Based on the above background, the inventors have designed a pipetting mechanism and a processing system for microbial solution detection to solve the above problems, and thus proposed the present application. Utility Model Content

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
