The low-temperature constant temperature reaction bath has a wide range of applications and can be used for low-temperature constant temperature experiments in industries such as scientific research, biology, chemical engineering, pharmaceuticals, food, physics, etc. Low temperature constant temperature reaction bath is a new type of mechanical refrigeration experimental equipment that can replace dry ice and liquid nitrogen for low-temperature reactions, and can also provide low-temperature circulating liquid for other experimental equipment, making it versatile. Install a magnetic stirring system at the bottom of the low-temperature constant temperature reaction bath to make the temperature inside the bath more uniform. Place the stirring element into the experimental container, and the magnetic stirring can drive the stirring element to rotate inside the container, allowing the experimental solvent to be fully stirred.

The sensitivity of the water bath determines the quality of the low-temperature constant temperature reaction bath, but there are also factors that affect the temperature control sensitivity:

(1) The faster the stirring speed, the more uniform the temperature of the medium in the bath, and the higher the temperature control accuracy.

(2) When the thermal capacity of the device is small, its accuracy in temperature measurement is higher.

(3) The low-temperature constant temperature reaction bath operates well and undergoes regular maintenance and upkeep, with a clean operating environment, which can effectively improve the temperature control accuracy of the low-temperature constant temperature reaction bath.

(4) The better the fluidity of the temperature medium, the more uniform the temperature distribution, and the higher the temperature control accuracy.
