Abstract

The invention discloses a constant temperature rotating device, which uses an actuator to drive the rotation of the copper cavity, which can control the temperature of the cavity and capture the fluorescent signal of each test tube in the cavity at the same time during the rotation process. The rotation of the body will drive the power line of the film heater to rotate. Correspondingly, two pairs of copper rods and their corresponding tracks are designed to solve the winding problem through sliding contact, and a single optical channel, a single excitation light source and a single light detector are used. The upper and side sides of the copper cavity improve the signal consistency between multiple tubes and achieve the consistency of multiple tube signals.

Description

technical field [0001] The invention relates to a constant temperature rotating device, in particular to an actuator that drives a copper cavity to rotate, which can simultaneously control the temperature of the cavity and capture the fluorescent signal of each test tube in the cavity during the rotation process. Background technique [0002] In the molecular detection market, Polymerase chain reaction (PCR) is currently the most widely used nucleic acid amplification method. According to the reaction temperature conditions, it can be roughly divided into two technologies: the first one requires temperature cycling (thermal cycling) , the second isothermal amplification (Isothermal amplification) technology that requires constant temperature operation to complete the amplification reaction. Since the latter amplifies the target nucleic acid under constant temperature conditions, unlike the former, the traditional thermal cycler is not required, and the overall system can be ...
