I cannot for the life of me figure out why i cant get past the bubble phase at full vac purge.
I keep the heat below 110F and cant get the past this phase after hours of running at full vac. I have one pittsburg 3 cfm 2 stage and a robinair 5 cfm stage and both cant fully purge. I am using a bestvalues degassing chamber five gallon. what could it be guys this is getting to be so frustrating

Its like they aren't able to finish the last stretch

All I use is a two gallon stainless soup pot on top of a 20 year old old heating pad with a vacuum pump I've had since 1983 . What does your vac. gauge show ?

gauge reads well below 30 i just dont understand why it wont finish. it just stays frozen with big tane bubbles. I use colibri i just dont get it....

Bubble phase at full vac and 110°………what does this mean? Because thc is boiling under those conditions...do you really think neither of those will purge? Just turn the vac down a touch, turn your heat down 5-10° and it won't take longer than a couple hours

My understanding is that Colibri is lighter fuel ONLY . Vector & Fast-Fill both claim 5 X filtered . If you are not pulling 30 , you must have a leak is all I can think of .

it says im pulling more than 30 sorry. yea im looking for a leak and cant find one. You think it might be pulling too hard?

the bubbles just wont pop they stay inflated indefinetly, ill give another hour its been 4. its only 5 grams..

"Im pulling more than 30 sorry. think it might be pulling too hard?"
See post #5
Don't go over 29.5 or lower depending on altitude

Amount shouldn't be a significant factor and many of us purge for less than an hour.......

ok ill try right now

Difficult , at best , to say without being there or seeing something .

This is what I get after 6-8 hrs. on , according to that thermometer , near 140 degrees .

it seems wierd to play with valves to get an exact 29 when my gauge is probably not that good to begin with. To reiterate your saying you have to be at exactly 29 or less to purge anymore pull and its not purging? Am i understanding this correctly?

the bubbles just wont pop its one big balloon wtf is this

Eveything qwiso just said is spot on.

ok will do

ok here the end result. nug run fail. why doesnt it work everyone does it and it makes a spider. fml and fuk this game

I wouldnt call it a 100% fail. Looks like ok shatter definately have seen worse. Whats your elevation?

Your gauge might be fucked. A lot of them come fucked from on line sellers. If it says it's pulling over 30 I would guess it's fucked. Go to an auto supply parts store and ask for an Hg vacuum gauge. They are like $10. Make sure the fittings on in are the same as yours or you will need to adapt it to fit.

How do you know your oil is at 110F? What are you using to know that? Or are you going by what temp your griddle says?

Well, if you're that easily discouraged, maybe you should just give up and never try again. I'll come pick up your chamber and pump next week...

Lol Meta!!
Hey Op

Don't get discouraged brother.
The oil/ vac purge process takes some hands on practice...

Don't jump into it with your best 2 oz of material.

Start small with relatively cheap or free material (a trim from your or a friend's harvest)

The nuances of utilizing a vacuum pump and altering atmospheric pressure to degas resins is not for the feeble motivation.

When you are at that stage and bubbles won't pop, release the vac and let fresh air in...
The bubble will collapse...

Close valve again, and the bubble will again inflate...repeat until it stops..

Do NOT go all the way up to full vacuum doing this..
As QK pointed out....

You can easily chase away the fish you are trying to catch, by boiling away THC under a vac.
The bubble has a ” skin”...

After inflating and deflating...the skin will eventually vanish from the heat.
Get rid of the skin.


Do not over purge.
No higher than 115°
105-110° under vacuum.
