Application of Semiconductor Thermoelectric Cooling Technology in Dry Thermostat

The dry thermostat is a constant temperature metal bath device controlled by a microcomputer to replace the traditional water bath device. Widely used in bioengineering, cell culture, clinical trials, genetic immunity, plant chemical industry, sanitation and environmental protection, and factory and enterprise laboratories for direct heating and constant temperature of trace samples, for sample preservation, preservation and reaction of various enzymes, nucleic acids and proteins Denaturation treatment, PCR reaction, electrophoresis pre-denaturation and serum coagulation, etc.


The dry thermostat using semiconductor cooling technology perfectly applies semiconductor cooling and heating functions, which greatly shortens the time of experimental operation. It is an ideal automation tool for sample incubation, catalysis, storage and other reaction processes. It has multi-purpose functions such as heating, cooling, and temperature customization.

The dry thermostat using semiconductor refrigeration system has the following advantages and characteristics:

1. Semiconductor cooling does not require any refrigerant and has no pollution source; it can work continuously for a long time and has a long life; it is easy to install. Metal module design, high temperature uniformity, easy module replacement. The performance of the instrument is more stable and easy to maintain.

2. The TEC can not only cool but also heat, so using one chip can replace the separate heating system and cooling system.

3. The TEC is a current transducing chip, and it can realize high-precision temperature control by controlling the input current. The instrument has precise temperature control and high stability.

4. The thermal inertia of the TEC is very small, so the cooling and heating speed is very fast. When the hot end has good heat dissipation and the cold end is empty, the TEC can reach the maximum temperature difference in less than one minute after being powered on. The heating speed of the instrument is fast and the heating is uniform.
