you did not. the ONLY posts you have made are in THIS thread.
you might want to read them again…I don’t see ANY that were not relevant to your initial post. I agree you’re not ready for adding a vfd to your pump, but it is absolutely relevant to not sucking too hard on your rotovap (which causes solvent to get past your condenser and to the pump).
THAT is correct pump choice…
NO IT HASN’T.
no modifications are necessary to achieve that. you’ve also been told what can happen with a pump that refuses to spit the liqour out…
I may not be the sharpest tool in the box but for what it’s worth… If you have sufficient “condenser area” and sufficient cooling capacity then what you are describing is the product of pulling too deep a vacuum on your system which does not let your vapor condense (if you pull a deep enough vacuum your solvent will stay as a vapor even at room temperature) and thus you are spitting out hot solvent from the exhaust of your vacuum pump (which by the way is a nice pump). If I may suggest adding a decent vacuum (pressure) controller to your system, it may solve most of your problems (when used correctly).
that sounds like the same irrelevant comment others have made…
@Rhyan1986; seriously, you may not have understood the “vac controller” or “pump on a VFD” comments, but folks are legitimately trying to help you here.
Which @Rhyan1986 has twice told us is an ethanol bath.
So my understanding of the story is clearly incomplete.
Even though I’ve read through this more than once.
The best guess I have is someone has put an extraction tank inside a thermo freezer, and told them it’s the “ethanol bath”.
That’s still a pretty useful trick at a certain point in ones game….even though they don’t really have the required cooling power.
There is at least one model that will take a 55gal drum.
The only other reasonable hypothesis is that thermo also make an ultrasonic bath, and they’re running ethanol in there against the manufacturers advice as @vortal notes is fairly common in some sectors.
This is the machine I am working with. I am sorry if it seems as if I am unresponsive, as I was trained on all of this very minimally and have been asked to figure it out myself, so I am a little bit overwhelmed with a lot of this information. So far what I have came to is that when the agilent dry scroll pulp gets back from the shop I’m gonna hook a cold trap in front of the pump. Then try to figure out why solvent is even getting back to the pump. I really wish I could talk to someone in a private message instead of a thread. Thank you all for your time.
If it’s out in the open, potentially dozens will learn from it…which also means that essentially all the information you need is just lying around here waiting for you to dig it out.
