1. PCR Amplifier

PCR is an in vitro DNA amplification technique. In the presence of template DNA, primers, and four deoxynucleotides, it relies on the enzymatic reaction of DNA polymerase.Through repeated cycles of three steps — high-temperature denaturation, low-temperature annealing, and primer extension — the target DNA fragment is exponentially amplified, enabling rapid acquisition of large quantities of the desired specific gene segment.

The PCR instrument is used for gene amplification, whose core function is temperature control.The most critical component for thermal control is the thermoelectric cooling chip used for heating and cooling in the PCR instrument.

The PCR cooling module designed by Huajing Thermostat adopts high-reliability PCRdedicated thermoelectric cooling chips from brands including Marlow, Daiwa, and Fulianjing, supporting up to 1,000,000 reliable thermal cycles.

The module heatsink designed by Huajing Thermostat uses either aluminum profile heatsinks or high-efficiency heat-pipe heatsinks.This design resolves common shortcomings in existing amplifier modules, such as edge effects, poor temperature uniformity, insufficient heat dissipation, and excessive weight that reduces portability.
