How to use the DLSB series cryogenic coolant circulation pump?
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.

How to choose a vacuum pump in the laboratory?
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.
