Got pump oil in my Errl! Experienced bho runners help!

I'm assuming it's because your mason jar doesn't have a valve, most desiccators should include one. You need to create a seal between the pump and the jar before switching it off or the pressure will try to equalize by sucking air and oil through the vacum back into the chamber.
You could try unhooking the pump while its still running, I have no experience but it seems like it would work.
Oh, and I would not recommend dabbing that oil!

 

info on what setup your using/ where you got it?

def interested on more info

 

What have you done since to fix this?

 

What kind of pump do you have? Most likely you have a defective pump. There's a devise in the pump called an Anti-suck back valve (ASV) that's most likely not working properly..I like to use dry scroll pumps myself.

 

Check out StupidStuff's thread on making BHO. Someone had this problem here:

People talk about putting things over their oil while purging to make sure they don't contaminate it. I think someone talks about this earlier on in the thread about how to prevent the backflow in the first place but I couldn't find it (having trouble with the new search feature).

 

I wrap mine in parchment paper fold it up like a sealed package, then put it in my chamber.  I also have the shutoff valve so I can turn it off before I turn off my vac.  You could have "winterized" with a solvent to reclaim your goodness

 

I would never recommend someone trying to save pump oil tainted errl. Thats just bad news, gotta move on and learn from it, definitely get a brass ball valve

 

dude that happened to me before, i just sold the oil for less money

 

 
what comes around, goes around

 

way to help out the masses.  if YOU wouldnt use it why would you let someone else?
