Problems solved by technology
When using this prior art in the purification step, the protruding portion on the circular cover directly punctures the sealing film covered on the nest chamber to carry out the purification step; the problem of this prior art is that after transportation, The surface of the outer envelope of the nest has a very high chance of being contaminated with contamination that confuses the result of purification, or, if it goes through multiple procedures during the process of handling and unpacking, there is also a great chance that the skin of the human body or animal will be contaminated. Pollutants such as crumbs, blood, sweat, etc. adhere to the surface of the sealing film. When the protrusion directly punctures the sealing film covering the nest, the pollutants will also be contaminated into the buffer, and the final output will be destroyed. Purity
[0005] The above-mentioned existing pipetting systems have their defects, so it is necessary to make further improvements to provide a sealing device that can avoid cross-infection caused by pipettes, and at the same time provide a tightly closed but easy-to-tear film device. , to avoid contamination on the surface of the sealing film from polluting the purity of the final inspection results, to overcome the shortcomings of the prior art

The invention discloses a liquor relieving device as well as a pipette and a series vessel used in the liquor relieving device. The invention particularly discloses a device for biochemical operations, comprising a pipette and a taper-shaped object which is provided with a hollow interior and extends along the axial direction. The pipette is provided with a first tail end and a second tail end, wherein, the first tail end is equipped with an opening while the second tail end is provided with a hermetic type volume-changeable gasbag. In virtue of the changes of the volume, a pressure difference is produced inside the hermetic type gasbag, thus realizing the release and suction of reagents in the pipette. The liquor relieving device also comprises a series vessel formed by connecting a flat slab part with a plurality of cells. The series vessel is pre-filled with various reagents in sequence needed by corresponding biochemical operations and is provided with a locking part. The liquor relieving device is also composed of an action control mechanism, a robot arm and a chassis; the chassis is provided with at least one groove which is equipped with at least one embedding part. The series vessel is fixed on the chassis through the mutual locking and clamping between the closing part and the embedding part in the groove of the chassis.
Description
technical field [0001] The present invention relates to a pipetting device, in particular to an automated method for nucleic acid purification, extraction, separation or screening using a pipette in combination with reagents prefilled in a series of multi-chamber containers Micropipette device. Background technique [0002] With the continuous and in-depth research on the human genome and functional groups, the research and development technology of life sciences for large-scale molecular biology is becoming more and more mature, such as: nucleic acids, proteins, enzymes, etc., and biological samples are often a mixture of various components. Its components are very complex, and the existing technology uses separation, extraction or heating to screen purified samples from blood, cells, etc. [0003] As the technology of nucleic acid purification has gradually matured, the operation steps in response to the purification process include setting up samples, adding buffer, addi...
