During the experiment, the air leakage from the rotary evaporator is very serious and will affect the entire experiment.How to solve the problem of rotary evaporator leaking gas? Let's take Re-501 as an example to explain the solution.

To detect where the rotary evaporator leaks, you need to check it step by step,First, first remove the re-501 rotary evaporator bottle and the receiving bottle of the evaporator, find other things, and then connect the rotary evaporator to the vacuum pump to observe the vacuum gauge on the instrument. If it can be kept for five minutes without pressure relief, the evaporation bottle and There is no problem in collecting the two interfaces of the bottle.The tightness of the four-way bottle on the rotary evaporator should be well mastered during installation.If it is because there is air leakage caused by tightening, remove the four-way bottle, reinstall it, and screw it until it stops.

The above are some analysis methods and solutions for leakage of the RE-501 rotary evaporator.In addition, in the process of detection, it is necessary to pay attention to the light part of the glass to avoid causing the glass to break.
