How to choose the vacuum pump used in the laboratory is a problem that plagues many users. After buying a vacuum pump, many users will encounter the vacuum gauge to observe that the vacuum is not enough (not enough suction), the pumping speed is too slow, and it is used in a relatively closed room. Excessive noise, or oil mist when the pump is in use, can not be used normally, and other problems. These problems are often related to the selection.
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.
