PCR pipe rack fixing and cooling plate

Abstract

The invention relates to a PCR pipe rack fixing and cooling plate. The PCR pipe rack fixing and cooling plate comprises an insulating and cooling flat plate, a left pressing block, a right pressing block, a rotating and positioning assembly, a flat plate fixing assembly and a T-shaped connection plate, wherein the left pressing block is fixed on the left side of the upper end surface of the insulating and cooling flat plate; the rotating and positioning assembly comprises an inner fixing shaft, a spring, an outer rotating shaft and a positioning rod with a bending hook; the inner fixing shaft is fixedly connected to the insulating and cooling flat plate through the T-shaped connection plate; the outer rotating shaft sleeves the outer side of the inner fixing shaft; the positioning rod passes through the right pressing block; the bending hook of the positioning rod is used for fastening a horizontal rod of the connection plate; one end of the spring is connected to the tail end of the positioning rod; the other end of the spring is connected to the outer rotating shaft; the right pressing block is mounted on the outer rotating shaft of the rotating and positioning assembly and is located at the right side of the upper end surface of the insulating and cooling flat plate. The PCR pipe rack fixing and cooling plate can be used for fixing PCR pipe racks, has certain pre-cooling and insulating effects and can also be used for solving the problems of cross contamination and nonspecific amplification caused by that the PCR pipe racks are light in weight and the temperatures of the PCR pipe racks easily change due to environmental influence.

Description

technical field [0001] The invention relates to a PCR tube rack fixing device, in particular to a PCR tube rack fixing cooling plate. Background technique [0002] There are following deficiencies in the existing PCR tube rack: [0003] ⑴PCR racks are made of plastic, which is lightweight. Because the material of the PCR tube rack is light and there are no fixed measures on the desktop, when adding samples to the PCR tubes, it often happens that the entire PCR tube rack is dumped or dropped without paying attention, resulting in the failure of the PCR tube rack. The full-page reagents fall off, which is easy to cause pollution and wrong samples. [0004] (2) Since the PCR tube rack is not fixed when the specimen is numbered, it is extremely inconvenient to write. [0005] (3) The PCR tube rack is made of plastic, so the temperature cannot be guaranteed. The PCR tube is easy to change with the room temperature, and PCR amplification requires a cold start to reduce non-spec...

Because the material of the PCR tube rack is light and there are no fixed measures on the desktop, when adding samples to the PCR tubes, it often happens that the entire PCR tube rack is dumped or dropped without paying attention, resulting in the failure of the PCR tube rack. The entire page of reagents falls, which is easy to cause pollution and wrong samples

[0004] ⑵It is extremely inconvenient to write because the PCR tube rack is not fixed when the specimen is numbered

[0005] (3) The PCR tube rack is made of plastic, so the temperature cannot be guaranteed. The PCR tube is easy to change with the room temperature, and PCR amplification requires a cold start to reduce non-specific amplification. Cool environment, and the existing PCR tube rack cannot meet this requirement
