In the process of using a rotary evaporator, pay attention to the following safety issues:
1.When the work is finished or the work is suspended, the vacuum should be released to prevent the sewage in the vacuum pump from flowing backwards.

2.The glass parts should be handled gently and cleaned, dried or dried before installation.

3.If the vacuum cannot be pumped up, check it:
(1)Whether the joints are sealed or not.

(2)Whether the seal ring and sealing surface are effective.

(3)Whether the vacuum grease between the main shaft and the seal ring is coated.

(4)Whether the vacuum pump and its hose are leaking.

(5)Whether the glass piece has cracks, chipping or damage.

4.If the solution is easily ejected during the concentration process, it should be eliminated by changing the degree of vacuum, lowering the temperature of the water bath, and slowing the rotation speed of the rotating bottle.
