Preventing Flooding During Reflux
« on: February 03, 2020, 05:52:46 PM »
I am very new to this forum, but have been a moderator at a very large pharmacology forum in the pretty recent past before I having to leave due studying. Nice to be here!

I posted this question in another thread I started but it wasnt the topic of the thread so I decided that I would make a new thread to discuss this issue.

I am wondering what can be done to help prevent flooding/clogging of a Graham condenser during reflux during a soxhlet extraction. An Allihn condenser would be ideal but in the event a Graham is used, what could be done to ensure that this does not happen? I was thinking a less vigorous boil might help slow rate of evaporation and condensation, but wasnt positive on this. Any thoughts?

Many thanks,
Mr. Deeds

It shouldn't be a problem. The only thing getting that far up would be solvent, which shouldn't clog it and wouldn't be enough to flood it.

Thanks. I have been very curious about that. I heard that the coils are not very efficient at letting the condensed liquid fall back into the chamber so I thought i would ask.
