Thermostatic circulating water bath is suitable for low temperature experiments in scientific research, biology, physics, medicine, chemical industry and other departments. It can replace dry ice and liquid nitrogen for low temperature reaction and provide low temperature conditions for related equipment. It can also be used as a low temperature water tank for viscosity test. It can also be equipped with magnetic stirring at the bottom and stirred in two stages to make the temperature in stainless steel tank more uniform and intelligent temperature control accurate.
