Experimental high and low temperature cycling deviceAs the core temperature control equipment in the laboratory, it achieves a wide range of temperature regulation from -80 ℃ to 300 ℃ through the coordinated operation of refrigeration and heating systems, providing a stable and controllable temperature environment for experiments such as chemical synthesis, material testing, and biological cultivation. It is a key support to ensure the repeatability and accuracy of experiments. ​

Wide temperature range precise control is its core advantage. The equipment adopts dual technology of compressor refrigeration and electric heating, combined with high-precision temperature sensors and PID intelligent temperature control system, which can control temperature fluctuations within ± 0.1 ℃. In chemical synthesis experiments, many reactions undergo multi-stage temperature changes of heating, constant temperature, and cooling. For example, polymerization reactions require heating to initiate the reaction, then maintaining the reaction process at a constant temperature, and finally cooling down to terminate the reaction. The experimental high and low temperature cycling device can automatically switch temperatures through a preset program to ensure that the reaction proceeds as expected; In the field of material testing, it can simulate harsh temperature environments, test the temperature resistance and mechanical performance changes of materials such as plastics and rubber, and provide data basis for material selection. ​

Flexible adaptability meets diverse experimental needs. The equipment is equipped with multiple interfaces and can be linked with experimental instruments such as reaction vessels, rotary evaporators, and electrophoresis machines to achieve temperature synchronization control of external devices; The circulation system adopts corrosion-resistant materials and is compatible with various heat transfer media such as water, silicone oil, ethanol, etc., to meet the requirements of different experiments on the media. In biomedical research, it can be combined with cell culture devices to simulate temperature fluctuations in organisms and study the effects of temperature on cell metabolism and proliferation; In environmental science experiments, the degradation patterns of pollutants at different temperatures are analyzed by simulating the temperature difference between day and night and seasonal temperature changes. ​

Intelligent operation improves experimental efficiency. The touch control panel allows for intuitive setting of temperature parameters and running time, and supports storage and retrieval of multiple programs; The remote monitoring function allows researchers to view the real-time operation status of equipment through computers or mobile phones, and automatically alarm for abnormal situations, avoiding experimental failures caused by temperature control. The application of experimental high and low temperature circulation devices has changed the traditional laboratory's reliance on a single temperature control mode of water bath and oil bath, and promoted the upgrade of experimental processes to automation and precision. ​
