Vac Chamber Purge Questions

[JointOperation]

ok.. so i got a chamber pump.. and all the tools n shit i need to make some properly purged bho.

now.. i know GW says 115F at full vacuum thin film is best..

but id like to hear what everyone is using temp wise. how long of a purge.. and what consistency you were aiming for and what you ended up with in the end..


how much can your tube hold..

how many cans of butane did you use?

how long is your initial purge ( The Purge Right After Spraying)?

do you do a hot water bath purge indoors before using your vacuum chamber and pump? and if so . for how long?

how long do you purge in a chamber and at what temps?

how many times do you flip your product before calling it DONE?

which strain ? and or is it a mixed batch.. nug or trim?

what yield did you get.?

what consistency is the product?

do you have any secret techniques that you are willing to share to achieve a properly purged very clean product..?

thanks to everyone in advance.. im just hoping to get enough information to see how everyones technique differs and how there product differs..

i personally think that this is a great topic and it could be very useful in helping anyone who is making bho.. to make a cleaner product..



also. im not trying to sell any product.. but.. i am using The 3 gallon ORANGE STICKERED Chamber off of Ebay.. if anyone else would like to post about its quality .. and any issues you might have had with it ..

A lot of purge times vary depending on the amount of material being purged and the amount of exposed surface area. I found that I can significantly reduce my purge times by doing a hot water bath and spreading the oil evenly over the pyrex until it looks like an even film. Then I put the entire pyrex into my vac chamber (plus side to a 15 gal chamber) and do most of my purge before scraping. Time depends on amount of material but usually do about 3 hours at 105 at 29.5 HG then scrape onto parchment and use a roller to flatten it. Return it to the vac at 105 for an hour or two. Flip the patty and back in the vac at 115 until finished. I single solvent dewax so I never have an issue with buddering. Kinda don't see the point in making shatter that's still filled with wax. You can't have truly stable shatter when you leave those waxes IMO.

The time, temperature, and vacuum levels depend on what you are trying to make.

The 115F at -29.5"Hg is only for shatter.

i just wanted to see some pictures of people extracts.. and know what temps they used to get therre and how long .

ive heard of people still seeing there oil react even after purging for days.. is this a extracting error? or

115f, heat purged for ~1.5 hours, vacuum purged for ~3.0 hours. During heat purge I aggressively use my heat gun (6 inches away on low) to speed up solvent boil off, water @ 115f top of oil never hotter than 120-124 from heat gun. I am impatient at times, I know it slightly cooks off terpenes, but the loss is minimal in my opinion, and doing a 112gram run takes 5 hours as opposed to 12-18 this way. Purging 10-22grams of oil.

You can reach the end goal (shatter, sap, wax etc...) several different ways. Some won't do what I do to preserve more terpenes, going with lower heat for longer times. A lot of it is observation and understanding oil. Once you play with it a few times you start to understand how it is reacting/why.

There is no rulebook where you can follow steps with time, temps, and vacuum level. There are rough guidelines for those variables, but they are usually changed (even slightly) every run, even if it is just amounts of time/heat.

What my method leaves me with - http://s1160.photobucket.com/user/daconic/library/?sort=3&page=1

115 +/- a few degrees because my heat source is laughable still... but it's fun, like sailing a ship.

Heated full vac for ~3 hours in a thin film.

i have been waiting on my butane to run this material.. but i grabbed 5 cans of ronson.. 5 cans of zippo... 5 cans of vector 14x .. 5 cans of power 5 x .. 5 cans of whip it 7x . and i just ordered some capital N butane.. ..

im really saving up for a closed loop system.. but honestly dont have the money right now. so im trying to find which works best for me.. honestly. if i had the money.. id do the tests that skyhighler did.. but i just dont have the cash to buy cases of each kind.. and then just spray them and not use it to extract... or else id be all over it..

Once you get the residual test down pat there's no reason to test more than a can or two of any particular brand, as the results are very consistent. Shoot cans of Ronson and Power 5X to bags, even without weighing them you'll probably never use Power 5X again... ;-) Ugly stuff compared to the best of the best.

 

[JointOperation]

ya. honestly.. the last time i did a test.. ronson came out better then the vector and the power.. but now i have the EXACT same Material in each tube.. so we will see the REAL difference..


honestly i liked the product the whip it made the first time i made it.. but ive noticed.. that even the worst butane.. if purged properly.. is better then alot of the commercial BHO going around.

 

[JointOperation]

but.. i cant seem to find CASES of Ronson.. ANYWHERE..

its wierd.. even hard to find Zippo by the case.. its easy to find tiny cans of ronson. and zippo.. but no cases.. even walgreens is nope.. only 3 cans last time i was there.. and they said that was it. they dont sell enough to keep stocking.. and they wouldnt give me a fair price to buy it by the case or master case.. so i couldnt do it .

wat about whip it 7 or premium 400ml cans?

Zippo makes Ronson canned butane, same stuff. Ronson's probably an exclusive deal with Walgreens, but Burn Wholesale has the big cans of Zippo, and if enough of you request cases they should be able to deliver, they're one of the biggest cigar outlets in the US.

Whip-it! Premium is nice, but why not check out Ultra Pure and/or Special Blue 7X if you're interested in the least residuals with good availability and price?

 

[JointOperation]

screw it . if ur saying ronson and zippo are great for canned tane.. ill go with that. but if these others that ur talking about are better.. let me know asap lol. i appreciate the work u did on that .

what about pure zho or the other mz whatever it is.. i hear people loving that shit for passive systems..

Few results posted up so far of experiments with MZ12X, I have a suspicion most everyone's waiting for Gray Wolf to give us his results on product yield, color, and scent.

Someone needs to invest in a warehouse load of Zippo and pander to the BHO community. Ought to do it myself.

Both Capital and Purtane have cleaner product coming out in the next month. Let's see if they can beat Zippo...

I have most of the pieces accumulated to run the test in passive recovery. Still missing two high pressure clamps, that were due last Friday.

Gray Wolf ...
i cant say it enough.. thank you for all your amazing work.. you are one of the biggest assets to this community.. i really appreciate all the info you bring to the table.. without Gray Wolf . i bet there would be alot more CRAPPY bho going around. then there already is..

and SkyHighLer

i cant thank you enough for taking the time out of your day to post and help people like me out.. we also appreciate the work you have done with the butane testing.. for the community.. that information is very valuable.. and your are thanked for that..


if i could afford a closed loop.. i would be all over it.. but the bills got the best of me.. and i have to run passive for a few more harvests .. hopefully..

^^^^^ This! QFT!!

My question pertains to the vac pump, and should I keep it running the whole time I'm purging or just close the valve when the vac chamber reaches max and turn the pump off while heat purging?.

I noticed that when I turn the pump off for say 20-30min while purging at full vac, the bubbling stops, the gauge still says its at full vac, but, if I turn the pump back on and open the vac chamber valve the material will start to bubble slightly again for a min or two, this says to me that I do need to keep the noisy pump running during the whole purge, even if it 24-48hrs?????.

What do you all think?.

 

[HashoftheTitans]

You don't need to run your pump continuously. You don't want to pull a full vacuum. The max I vac to is 29.5inHg. Once you have reached that you can valve off the chamber and shut the pump off. You may lose some vacuum from off-gassing of the solvent. If this happens, just vac it back to your desired level. This will save some wear and tear on the pump.

i found out that u can boil thc away at full vacuum at ambient temps.. this is why people say -29.5 max vac.. anything after that and u can lose goodies you want. and i noticed the same thing.. but i learned to flip it alot. .and now i got some nice bho that doesnt spark up at all no butane left.. amazing taste and smell and the potency is out of this world.. about to run a half pound of buds today or tomaro for bho. cannot wait.
