Product Description:
Low temperature coolant circulation pump is a low-temperature liquid circulation equipment that adopts mechanical refrigeration, and has the function of providing low-temperature liquid and low-temperature water bath. Combining rotary evaporators, vacuum freeze-drying ovens, circulating water vacuum pumps, magnetic stirrers, and other instruments for multifunctional low-temperature chemical reaction operations and drug storage. Low temperature coolant circulation pump can be matched with various instruments (rotary evaporator, fermentation tank, chemical reaction kettle, freeze-drying equipment, biopharmaceutical reaction kettle, etc.); Large cooling capacity and fast cooling speed greatly improve work efficiency; The flow rate of the local circulation pump can be adjusted or customized, greatly meeting the actual needs of different users.
Product features:
The large capacity open bath and external circulation are integrated, which can serve as a freezer and provide cooling liquid to the outside.
Temperature digital setting and display, easy to operate.
The key components such as refrigeration compressors are made of well-known brands from the United States, Germany, and France, with high reliability and efficiency.
The circulation system adopts ANSI304, 316 and polymer anti-corrosion materials, which can prevent rust, corrosion, and low-temperature liquid pollution.
