Low temperature constant temperature reaction bath, also known as low-temperature constant temperature bath, low-temperature bath, low-temperature reaction bath. It is a low-temperature constant temperature instrument that our company has improved and produced based on the low-temperature coolant circulation pump. It has the function of heating (auxiliary constant temperature), which makes the temperature control accuracy higher; Install a magnetic stirrer at the bottom of the constant temperature bath. When the magnetic stirrer is working, it can make the medium solution in the low-temperature constant temperature reaction bath flow, achieving a more uniform temperature in the low-temperature bath and more accurate temperature control. At the same time, it can also make the test liquid flow under the stirring of the polytetrafluoroethylene stirrer, making the temperature of the test solution more uniform and the reaction more complete. According to customer needs, a circulation pump can be added to the equipment to achieve the effect of a low-temperature coolant circulation pump, achieving the goal of multi-purpose use for one machine. Low temperature constant temperature reaction bath is suitable for conducting low-temperature experiments in scientific research, biology, physics, medicine, chemical engineering and other departments. It can replace dry ice and liquid nitrogen for low-temperature reactions and provide low-temperature conditions for related equipment. It can also be used as a low-temperature water tank for viscosity testing.
