Multi-chamber sample preparation box

Abstract

The invention provides a multi-chamber sample preparation box. The preparation box comprises a box body, wherein a central through hole is formed in the box body; the central through hole penetrates through the top wall and the bottom wall of the box body; a plurality of containing cavities are formed in the periphery of the central through hole and are isolated mutually; a reaction tube is further formed in the box body; the reaction tube extends out of the vertical wall of the box body; the reaction tube can be communicated with reaction tube pretreatment cavities in the plurality of containing cavities; and the reaction tube and the box body are integrally formed in an injected molding mode. According to the preparation box, the reaction tube and the box body are subjected to integral injection molding, so that the potential risk of sample liquid leakage caused by assembly and connection of the reaction tube and the box body in the prior art is effectively avoided, and the sample preparation box is simple, convenient and more reliable to produce and use.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection, in particular to a multi-chamber sample preparation box. Background technique [0002] The popularity of nucleic acid detection technology is getting higher and higher. At present, the most widely used instrument is the nucleic acid amplification instrument. It needs to be placed in a professional laboratory that meets specific biosafety requirements, and the experimental operators must also undergo strict training. On duty operation. This is because this kind of instrument can only run the nucleic acid extracted from the sample, and the nucleic acid extraction process needs to be carried out precisely step by step. These steps are complex and highly repeatable, including dilution, quantification, shaking, centrifugation, fusion and other operations. Add various solutions quantitatively, and some of the operations are repeated operations. Finally, the sample that has completed nuc...

Problems solved by technology

One of the widely promoted products includes a box body and a reaction tube detachably connected to the box body. This detachable structure of the reaction tube can facilitate the replacement of different types of reaction tubes, thereby improving the versatility of the box body. However, there is a defect in the connection between the sample liquid channel on the reaction tube and the sample cavity of the box body. The existing treatment method is to set a gasket at the connection between the two, and the gasket can prevent the sample liquid from leaking to a certain extent. However, there may still be a situation where the seal is not tight, especially when the reaction tube is disassembled many times or the socket is not in place, the sealing effect of the gasket will be significantly reduced
