My purging process..

[Pisces]

water baths are beyond un-even in temps there never maintainable.

sorry…but i'm gonna hafta disagree with you here.

I too use a griddle…But Only after all larger butane bubbles have stopped popping!

Water baths "over" a griddle allow for evenly distributed heat around the bottom AND the sides of the pyrex..whereas a plain griddle has hot spots and can only heat the bottom.

With a water bath, temps stay even for longer durations without too quick of fluctuations.

I only use the water bath to remove butane…then it's straight to the chamber, then winterization and purged further.

I've been making Absolute Amber for longer then two years and have never had water mix with my oil.
Never~

This is the back of the griddle i use. I believe the male end just heats up the steel and doesn't cause a spark...

Theres more than one way to skin a cat my friends. Just agree to disagree and move on.. Either way can be the correct way if it works for you. Chill,,,

The problem is that what's working for him might maim or injure someone else.

 

[squiggly]

I was simply curious why.. was not really looking for an attack but thanks :D It gave me something else to do today besides buy a new chair and rearrange my entire basement :D

I told you why, and you argued and argued and argued.

Was I supposed to just bitch up and say, "yes little dabbie--your much more dangerous way that offers no benefit is better. What was I thinking?"

Next time you ask a question, expect an answer.

If you choose to debate the answer, expect a debate.

Also, if you're speaking with me and suggesting that people do something dangerous--expect me to call you on it.

That simple.

LOL I dont even know what to say to you squiggly... Keep on truckin.. :D

Do either of you guys know at what temp oil turns to a molten state? I put my vac on a heating pad and got a temp of 95* on my oil but it wasn't loose enough to have any reaction to the vac. What is the temp window for purging my oil? ( min-max) And do i get to the vac i want and close the valves and turn off the pump Or do i need the pump to be continously running? How long does purging typically take? I purged my shit for an hour!! But it kept getting cold then hot then cold.. I was also looking at it.. And playing with the setup..

1. Heat the material (i use a heat gun).
2. Get it into as thin a film as possible.
3. Place in the vaccum chamber (making sure it's still heated after you spread it out--heat again if necessary)
4. Pump down to -29mmHg and hold it there for 2 minutes or so (continuously running the vacuum pump--turning it off before releasing the pressure is bad for the pump)
5. Release pressure. (slowly for the sake of your pump)
6. Pump off.

Repeat this until it bubbles no more under vacuum.

Temp will be dependent on what strain your working with..

Min 75 Max 120 range could go as high as 130 with some strains it really does depend on the strain age of material cure process flush so many variables which is why i said your gonna need to play around at this for a while...

My pump stays running if im running oil so is my vac.. when it stops the oils done.. Short of me turning it off to check the temp of the oil..

Purging again depends on strains..

yeah cold hot cold hot no good for purging you want a continues heat source while purging.

Also if you close both valves on your chamber and shut your pump off and leave the hoses connected you will create a reverse vaccume on your pump its self and you will drain the oil right out of it and right into your vac line and then if u open 1 off the valves its gonna shoot it all into yer chamber.

So remember kids 1. Dont tighten the exhaust ports :D

2. Don't leave the pump under a vaccume unless the pumps running.. Otherwise dissconnect the hose or turn the ball valve if you have one to a position where you can release the vac on the pump but not the chamber. :D

Both of you guys rock!! Thank you for being patient and helping me out. My first batch is a shitload better than anything ive done before so im off to a good start. It actually has taste!! Ill just keep practicing with small batches and improve as i go hopefully.

It doesn't matter if you cycle between cold and hot, we're getting firmly into my wheelhouse of actual expertise here (chemistry) so I can say that with a considerably high degree of authority.

The most important things here are:

1. Thinnest film possible.
2. Highest heat (and thus lowest viscosity) possible at the time of placing under vacuum.

Ideally you will want to stir the mess up quite a few times between purges because the thinnest film you can get isn't anywhere near thin enough. Even with max heat applied the stuff is just much too viscous to get it all out without this step (which requires you to pump down multiple times). To my knowledge there is no way to avoid this step unless you have a method for dispersing an EXTREMELY thin film for a single run. The surface area required for this without some fancy engineering is much too large to fit in a vessel in your vac chamber--or even spread out directly on the bottom of it unless you're working with very little oil.

If you have a rotary evaporator (what would be used for this process in a laboratory), as I'm sure you don't, you can get around this by rotating a vessel which constantly disperses a thin film (and stirs the material). This allows for maximum removal of solvent.

Putting the stuff in a relatively big blob and heating it just doesn't cut the mustard. It's too viscous of a material even under the most ideal of conditions for this to effect complete removal of the butane.

Can you get it to stop bubbling doing it this way? Yep--but there's still plenty of butane in it, guaranteed.

(There will be some left anyway--even using a rotovap).

Keep at it :D And show off in the concentrate porn thread!!

My first batch!! Had the temp at around 130 degrees and purged for a couple hours to make sure. I did notice that under 130 degrees i didnt get any movement from the oil and it was soft,, but not molten. So i would turn up the heat for 10 sec or so to really see it melt then i would immediately take off the heat so it wouldnt get too hot. This is made from regular weed and im quite pleased with the results!! So shatter isnt suppose to "shatter" .. I get it now!!!! Im liking the shatter now. Thanks again guys

 

[LittleDabbie]

Good job :D

 

[mikeb437]

Dont know what i did to make it turn into earwax but im lovin it!! I used some killer buds too so that probably made a big diff...

 

[SexOG]

You're the first person I've come across who *doesn't* want shatter lol

I didnt know what real shatter was till i bought my vac purger. I thought the crap i was making was shatter but it was just dirty dirty oil. I love the shatter now!!

You didn't take out the waxes.

Yea, without purging it's poison!

 

[Jeckle]

Yes, you will get an oil that is PROPERLY purged with temps that low.

If you don't want shatter, which is nothing more then correctly purged Wax…then all you have to do is fuck it up!

Turn up that heat….and whip the shit out of it!

Go ahead man, trap all that butane, wax, moisture and fats that you pulled from the plant matter.
Then when your nail is full of black chaR and your head and lungs hurt, you'll know why!

Peace, Picses

Exactly that dude, get clean shatter then aim for honeycomb , if your oil waxes up unintentionally that just trapped butane preserving the oil, autobuddering as they call it is not what you want, and also I think one solvent is enough if smoking, to winterise would be a pointless added solvent onto an already solvent extraction , get a dewaxing system save adding solvent to solvent
