DEVICE FOR THERMAL CONVECTION POLYMERASE CHAIN REACTION

摘要

Provided in the present invention is a device for thermal convection polymerase chain reaction (PCR). The device is used for bearing a test tube such that PCR is performed in the test tube. The device comprises a heat radiating base which has a body and a passage provided through the body to be used for the insertion of the test tube wherein the passage has a large diameter section and a small diameter section positioned below the large diameter section. Therefore it can be ensured that during the PCR process the surface temperature of the mixed liquid is lower than the temperature required in a primer annealing reaction.
