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.
The rotary vane vacuum pump is an oil-sealed mechanical pump that achieves gas extraction by utilizing a rotor to drive vanes in an eccentric rotation, thereby altering the volume of the pump chamber. It is widely employed as a backing pump and for providing low-vacuum environments in scientific research and industrial settings.
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.
