PCR moving device and PCR instrument

Abstract

The invention provides a PCR moving device and a PCR instrument, and relates to the technical field of PCR detection. The device comprises a first mounting part, a first telescopic part and a second telescopic part; a first side of the first telescopic part is movably connected with a PCR body, and a second side of the first telescopic part bears the first mounting part; the first telescopic partis used for moving the first mounting part into the PCR body from the outside of the PCR body or moving the first mounting part out of the PCR body; the first mounting part comprises a moving seat forplacing a sample module; the first end of the second telescopic part is connected with the moving seat, the second end is connected with the first telescopic part, and the second telescopic part is used for moving the moving seat upwards or downwards. With the device, problems of poor stability and low detection precision of the PCR device caused by the movement of the optical system are solved,and thus the beneficial effects of improving the detection precision and the detection efficiency are realized.

Description

technical field [0001] The invention relates to the technical field of PCR detection, in particular to a PCR mobile device and a PCR instrument. Background technique [0002] The basic principle of the polymerase chain reaction PCR (Polymerase Chain Reaction) instrument is to amplify DNA fragments through heating and cooling cycles, and its core is a temperature control module. The Real-time Quantitative PCR Detecting System (Real-time Quantitative PCR Detecting System), that is, the QPCR instrument adds an optical excitation and detection system to the traditional PCR instrument. At present, the temperature control module of most QPCR instruments on the market is fixed, and the purpose of pressing with the test tube is achieved through the downward movement of the optical module and the thermal cover. However, such solutions often have the problems of poor stability and low detection accuracy of the PCR device due to the movement of the optical system. Contents of the in...
