The cryogenic coolant circulation pump adopts a cryogenic liquid circulation device that is mechanically cooled. It has the function of providing a cryogenic liquid and a low temperature water bath. Combined with rotary evaporator, vacuum freeze drying oven, circulating water vacuum pump, magnetic stirrer and other instruments, the chemical reaction operation and drug storage under multi-functional low temperature are carried out. It has the functions of providing low temperature constant temperature liquid bath, low temperature constant temperature condensation cooling, low temperature constant temperature storage, establishing a second low temperature constant temperature field, etc., and is widely used in medicine, chemical industry, scientific research experiments and the like.
The cryogenic coolant circulation pump is a combination of a circulating pump and a cryogenic cooling pump. It is a good auxiliary equipment for vacuum distillation and vacuum concentration. It is especially adapted to be equipped with a rotary evaporator, which not only reduces the use space, but also reduces the vacuum degree and saves water resources. It is widely used in modern laboratories.
A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space.
