60+ grams of oil covered in vacuum pump oil..

funny, I ran my pump for 5 minutes last night, got to full vac, woke up, and my shit was fully vac purged.

the pump sounded the exact same when sucking on the chamber, or sucking on the ball valve after I closed it... nothing!

when I woke up, I ran the pump, let it suck on the empty line and the closed ball valve for a bit. observed its sound... open the ball valve and pay close attention to the sound because if there was any degassing overnight, and it lost even 1 or 2% vacuum, the already running pump would now be making a different sound until its reached max vac again... as well as the gauge might move, which mine doesnt. maybe I just need a fancy expensive accurate one.

I dont know...maybe im stoned, but it kind of reminds me of a snow plow... you can only plow so much snow until youve got a mountain in front of you and youre just sitting there spinning the tires forever. one youre at max vac its max vac. plain and simple. the degassing rate after the few first minutes is nowhere near the same as what the pump is sucking therefore major major overkill. especially if youve purged it somewhat properly to begin with before chamber.... ive seen how much butane is in some of your oils when going into the chamber...crazy!!! I boil 98% of the butane off outside and vac chamber for the other 2%.. ive seen videos on youtube and pics here of butane that looks like 25% butane weight, now that stuff would require a running pump for the first few minutes id imagine. but overnight or 36 hours... thats just asking for trouble. too much risk, no reward. fuck that.


not saying whats right or wrong, just some food for thought for the new guys that are reading this.

Maybe that's just it, the majority seem to be going in with a full gel on their hands so running continuously till you get down to something is most likely with the mentality of it being an expedient comes from. It sounds like your going in with purge shatter to begin with so your analogy of the snowplow would seem poignant.

well

I got these manifold gauges from harbor freight and all i can say is i will be returning asap,

The gauges i use now are more accurate, it doesn't have a micron reading at all its just a tiny in/hg gauge.

The ones im using now are the ones from the mityvac hand pump at harbor freight. its a full size 0-30in/hg gauge pretty descent, more accurate in my eyes.

This one i bought i though had a micron gauge, but i should of known the HF isnt that cool.

is my only option for a micron gauge online?

There are 760,000 microns in one atmosphere, and THC starts to boil at room temperature, so we only pull to -29.5" Hg. That means that there are about 106,684 microns left in the chamber. I can easily read 29.5" Hg on a gauge, so I don't consider the extra numbers as necessary.

this bit of info that i have read from fade in the past is the reason i dont make the crumbly wax anymore i pull it out right before that its starts to get that way and i have noticed a difference in potency, and so have everyone else that gets my wax.

so if you read and acknowledged that, why do you still run your pump all day and night trying to achieve and keep a 100% vacuum , when FD said that a 100% vacuum is not only not required, but its preferred.

you should also be noticing a huge flavour increase too. I know I did.

I open my back valve so I have the pump constantly sucking on the oil, but its maxed out at 29.5 in/hg

But it wasnt finished when i went to sleep so i closed valves and in the morning it was purged and i still had full vac

My conclusion is that leaving pump running will shave 3 hrs avg. off your purge time..
other wise if you got time to wait close valves and let it sit is fine

but I run at least 2 -3 lbs a week and I purge alot of oil, so having my chamber being taken while other slabs are waiting to go in isnt time effective,

When this 60 grams of oil got covered it was actually 2 different batches in the chamber on seperate pieces of parchment.

hmmm, now this im not 100% sure id agree with. maybe fadedawg can give us some insight.

Running the pump constantly will make it faster, just not by a whole lot.

Once you pull the levels down to -29.5" Hg, there are very few liberated solvent molecules floating around for the pump to get hold of, so valving it off and shutting down the pump allows the molecules to accumulate and when you turn the pump back on, they are quickly evacuated.

I turn off the pump, to save wear and tear on it, but leave it running if I am in a hurry, because the pressure rises above -29.5" Hg as the molecules escape from the solution.

Hey I'm new to this wax making and I purged with vac running for 20 plus hours and I have a pile of light yellow amberish sticky as hell oil. Would appreciate a step by step with all the little nuances of properly purging to get wax and shatter. I've gotten wax by leaving it in Pyrex pan at 95 degrees but it's still not clean in my opinion but like I said I'm new and just want to make the cleanest and safest I can. Thanks

sounds like youre close.

dont leave the pump running... thats just asking for disaster.

get full vacuum and let it sit for 24 more hours at 110f heat and it should wax up, or start to at least...

wax doesnt mean its perfectly safe. if youve been in vac for 20 hours, at room temp it should be pretty stable to handle, and safe at that point... in regards of butane.

now the biggest concern should be the plant waxes that are still in that oil which cause your chest burn and youre not able to inhale without a coughing fit... its not the butane doingthat ;)
