Heating device of multi-channel nucleic acid detector

Abstract

The invention relates to a multichannel nucleic acid detector heating device, which comprises a placing table, the top of the placing table is provided with a plurality of mounting seats, the top surface of each mounting seat is provided with a containing groove, the groove bottom of each containing groove is provided with an electric heating piece, the side wall of each containing groove is provided with a contact piece, and the contact piece is provided with an electric heating wire. The electric heating piece and the contact piece are electrically connected with the same external power source, an electrode connected with the electric heating piece is opposite to an electrode connected with the contact piece, a taking and placing base is arranged on the side wall of the installation base, a heat conduction bearing plate used for placing a detection chip is arranged on the side wall of the taking and placing base, and a contact plate is arranged at the bottom of the heat conduction bearing plate. The contact plate is arranged in an L shape, the bottom side of the contact plate makes contact with the top side of the electric heating piece, the side wall of the contact plate makes contact with the side wall of the contact piece, and the top of the installation base is connected with a cover plate used for sealing and covering the containing groove. The method has the effect of reducing the energy consumption of the heating and heat preservation detection chip.

Description

technical field [0001] The present application relates to the technical field of nucleic acid detection equipment, and in particular, to a heating device of a multi-channel nucleic acid detector. Background technique [0002] Nucleic acid amplification detection technology is to provide in vitro amplification conditions for nucleic acid fragments to exponentially amplify them and add fluorescent dyes or fluorescent markers during the nucleic acid amplification process, and use an optical device to detect the intensity of the fluorescent signal. In the process of obtaining the nucleic acid amplification result by analyzing the fluorescent signal, during the nucleic acid amplification reaction, the reaction system such as the detection chip needs to be heated. [0003] At present, the heating device of the nucleic acid detector is generally provided with an accommodating box, a plurality of accommodating grooves for placing detection chips are arranged on the accommodating gro...
