Product Description
Low-temperature circulating pump also know as Low temperature cooling water/ liquid circulation pump. This device adopt mechanical refrigeration, the main function is providing low temperature liquid, low temperature water bath . It can also connect with rotary evaporator, vacuum freeze drying oven , cycle water vacuum pump , magnetic stirrer and so on , to achieve the chemical reaction or drug store under low temperature condition. Large cryogenic cooling liquid circulating pump is constant flow, constant voltage. It is a necessary lab equipment for medicine, chemical industry, food industry, metallurgical industry, universities, scientific research, genetic engineering, polymer engineering and so on.
