How to solve the leakage of the rotary evaporator

Rotary evaporator is an evaporation instrument widely used in laboratories. Leakage is a common failure phenomenon of rotary evaporators.In the process of use, you should pay attention to frequent detection. Then, by what method can you detect the leakage fault of the rotary evaporator?

1.In the event of a leak, use a phenolphthalein test strip for the leak, because ammonia is alkaline and the phenolphthalein test paper turns red.

2.When the rotary evaporator is overhauled, if there is no frost somewhere, this is a leak point;

3.It can also be tested by soapy water;

Through the above three methods, the leakage point of the rotary evaporator can be detected. In the detection, the three methods can be selected one by one, and the rotary evaporator must be checked regularly to avoid affecting its normal use.Rotary evaporators are suitable for reflow operations, rapid evaporation of large amounts of solvent, concentration of minor components, and reaction processes that require agitation.The rotary evaporator system can seal the pressure to 400~600 mmHg; the solvent in the distillation bottle is heated by a heating bath, and the heating temperature is close to the boiling point of the solvent;At the same time, the rotation can be performed at a speed of 50 to 160 rpm, so that the solvent forms a film and the evaporation area is increased.In addition, under the action of a high-efficiency cooler, the hot vapor can be quickly liquefied to accelerate the evaporation rate.
