Problems solved by technology
[0004] When the traditional sampling needle is used to extract the reagent and transfer it, because there is a large amount of space above the reagent in the sampling needle, the reagent is likely to shake in the sampling needle when it is moved and carried, and it is easy to cause the components of some special reagents to be inactivated or otherwise damaged. situation, and the sampling port at the lower end of the sampling needle is likely to cause leakage of reagents, affecting later experimental work

The invention relates to the technical field of reagent sampling, in particular to stable pipetting equipment for reagent sampling. The equipment comprises a sampler shell, a liquid storage bin, a driving cavity and a piston, and further comprises a sampling tube which is movably arranged on the sampler shell and communicated with the liquid storage bin; a monitoring module which is arranged in the sampler shell and is used for monitoring the content of the reagent in the liquid storage bin; a first valve module which is arranged between the sampling pipe and the sampler shell and is used for controlling opening and closing of the sampling pipe; and a second valve module which is arranged between the driving cavity and the liquid storage bin and used for controlling the communication state between the driving cavity and the liquid storage bin; wherein the monitoring module is electrically connected with the first valve module and the second valve module, and when the content of a reagent in the liquid storage bin reaches a set threshold value, the first valve module and the second valve module work; the whole device is higher in stability, and the component integrity of the reagent can be effectively protected.
Description
technical field [0001] The invention relates to the technical field of reagent sampling, in particular to a stable pipetting device for reagent sampling. Background technique [0002] Chemistry is a kind of natural science. It mainly studies the composition, properties, structure and changes of substances at the molecular and atomic levels, and creates new substances (essentially, molecules that do not exist in nature). Unlike particle physics and nuclear physics, which study smaller scales, chemistry studies the material structure of atoms-molecules-ions, chemical bonds, intermolecular forces, and other interactions, and its scale is the closest to the macroscopic in the microscopic world. Their natural laws are also most closely related to the physical and chemical properties of substances and materials in the macroscopic world in which human beings live. [0003] In the chemical experiment process, it is often necessary to use a pipetting device to transfer the reagent i...
