Low receiving rate while evaporating is good.
Vacuum pump being corroded.
Harmful gas escaping.
Sudden solvent bumping.
You may often meet the below problems when operate rotary vacuum evaporator
, why these problems happen? How to avoid these problems? -
Why these problems happen?
Rotary evaporator system vacuum degree is higher than normal is the possible reason.
If vacuum degree is too high, will cause solvent steam temperature is too low so couldn’t be collected efficiently. Release vacuum is need, but other problems will happen if vacuum degree is too low.
How to avoid these problems?
TOPTION engineers suggest you to equip vacuum controller and low temperature cooling circulator for your rotary evaporators, so as to be able to hold at a proper vacuum rate and condensing temperature for an efficient, stable and safe operation.
