Abstract

The invention relates to a low pressure magnetic induction heating PCR temperature control device. The device comprises a heating chamber 1, a PCR reactor unit 2, a hollow metal disc 3, a coil 4, a refrigeration unit 5, a temperature control unit 6, a magnetic induction heating control unit 7, a main control unit 8, a stepping motor 9 and a temperature sensor 10. The PCR reactor unit 2 is locatedbetween the heating chamber 1 and the hollow metal disc 3. The hollow metal disc 3 tightly fits to the outer circumference of the PCR reactor unit 2. The magnetic induction heating control unit 7 is connected to the coil 4 and is connected to the main control unit 8 through vertical insertion connection. The temperature control unit 6 is connected to the temperature sensor 10. The temperature control unit 6, the refrigeration unit 5, the magnetic induction heating control unit 7 and the main control unit 8 form a heating-cooling cycle control system for the PCR reaction.

Description

Technical field: [0001] The invention relates to a magnetic induction heating device, in particular to a temperature control device suitable for polymerase chain reaction variable temperature PCR reaction. Background technique: [0002] Polymerase Chain Reaction (PCR) is a molecular biology reaction of DNA amplification. One of the key factors for the success of variable temperature PCR reaction is to meet the temperature cycle conditions required by the reaction entity, that is, high temperature denaturation, low temperature annealing, and medium temperature primer extension, so temperature cycle is its basis, and "variable temperature" in temperature cycle The rate will determine the specificity of the PCR reaction and the overall speed of the PCR run. The thermal cycle system of traditional PCR is roughly divided into water bath type, air flow type and semiconductor type, and the heating method is resistance wire, resistance sheet or semiconductor combined with heat cove...
