Description

PCR board convenient for film pasting

Technical Field

The utility model relates to the technical field of experimental equipment, in particular to a PCR plate convenient for film sticking.

Background

PCR (Polymerase Chain Reaction ) plates are used for in vitro amplification of genes, requiring constant changing heating and cooling of samples loaded on the PCR plates during the reaction. The kit can be widely applied to the fields of genetics, biochemistry, immunity, medicine and the like, is not only applied to basic researches such as gene separation, cloning, nucleic acid sequence analysis and the like, but also can be used for diagnosing diseases or any places with DNA and RNA, and belongs to disposable laboratory consumables.

In order to avoid evaporation loss of the reaction solution, external impurities fall into the PCR plate, and the PCR plate needs to be adhered with a sealing plate film. At present, most of the commercially available PCR plates are not designed with the film in mind, which requires great attention from operators in film sticking and increases the burden on operators.

Disclosure of Invention

The utility model aims to overcome at least one of the defects in the prior art and provide a PCR plate convenient for film pasting.

The aim of the utility model can be achieved by the following technical scheme:

the PCR plate comprises a tube plate provided with a mounting hole and a reaction tube provided with an adduction tube orifice, and the injection molding empty position is adjusted, so that the plate surface is smoother, and the adsorption and sealing performance of the film are facilitated;

the reaction tube is positioned at the mounting hole, and the inner pipe orifice of the reaction tube is contacted with the pipe plate.

Further, the diameter of the adduction pipe opening is larger than that of the mounting hole. The PCR plate can be stuck with a film, the pipe orifice is retracted, the contact area between the plate and the film is increased, the sticking is better, the evaporation is reduced,

the edge of the pipe orifice and the plate surface are in transition more smooth, so that the film is prevented from being scratched.

Further, the tube plate is made of one of PP or metal.

Further, the tube plate is provided with a trapezoid chamfer. The chamfering function plays a role in positioning, so that a plurality of PCR plates can be stacked conveniently.

Further, the tube plate is provided with a skirt edge. The skirt serves to provide stability support for the pipetting process when constructing the reaction system, and mechanical strength and grip when incorporating automated workstations

Further, the material of the reaction tube is PP. PP is a very good heat-resistant inert substance and is used at a temperature ranging from-30 to 140 ℃.

Further, the diameter of the tube body of the reaction tube is equal to the diameter of the mounting hole.

Further, the reaction tubes are distributed in a rectangular shape of 8 x 12.

Further, the height of the reaction tube is less than or equal to the height of the tube plate.

Further, the lower half section of the reaction tube is a hollow cone with a closed bottom, and the upper half section is a hollow cylinder.

Compared with the prior art, the utility model designs the inner pipe orifice, increases the contact area of the pipe plate and the film, ensures better lamination, reduces evaporation, and has the advantages of smoother transition between the edge of the pipe orifice and the plate surface and preventing the film from being scratched.
