Vac purge

I don't fully understand the process of purging, should your pump always be on? When my pumps conctantly on it reaches - 30 hg which I'm not sure is good. I've tried having the t valve and release valve shut and the pump off I've also done it with the pump on. Or with the t valve open and the pump running which is when it reaches -30 hg. Can someone help me on this? Anything helps

The pump does not have to be on continuously , let her run for 10-15 minutes and close the isolation valve and shut the pump off.

You can go back and pull another vac every few hours or so,keep the valve shut until the vac is turned back on.

What kind of pump are you using ?

Are you at or below sea level?

I'm using a pump that came with my vac it pro, it's no name but it's a 1 stage 3 cfm and the ultimate vacuum is 5pa, also I'm at sea level

No problem bro,

Sounds like you are doing just fine, probably your gauge may need calibration, or just try giving a little tap with your finger on the face of the gauge.

Further questions?
Feel free to post em up.

And thank you for the thank you my friend.

Ok thanks, Ive only had a vac purge for a short time so this batch was my third time using it and each time I ended up with a honeycomb cookie. I wanna try and make shatter and was wondering should it wax up first then turn into shatter? Or should it just turn into shatter? With constant low temps

with a vac chamber.,. as long as u can keep your temps constant.. you should be able to make any kind you want.. usually i see that honey comb effect after very long purges at higher temps.. but at 110-115.. and pulling vac.. u should get to the point were it looks like a pool of oil with a few bubbles.. i flip the patty a few times to get everything out.. and usually end up with a nice shatter product.. unless i use nugs.. for some reason i cant get my nug runs to shatter .. there more taffy snap and pull type of shattery. but they REAK like nugs.. so i think terpenes has alot to do with it .

ive noticed alot of people seeing wax and honeycomb.. but really it was they were purging the oil at the correct temp.. and the temp dropped low and hardened the material.. like that.. and people think THATS WAX OR HONEYCOMB.. i remember showing a friend. fake honeycomb no chamber.. just pull it out of your pyrex early.. and allow to bubble up on heat and cool.. looks identical to honeycomb except there is tons of butane in it... alot of the stuff going around either was ran using too much butane.. causing it to be sappy because there extracting stuff that doesnt hardened up.. and or because theres butane still in it .

Shatter, ahhhhh she is an elusive lady eh?

The first 2 suggestions should produce a hard brittle resin.
*Use fresh material, 5-10 ,,,days from clipping. Do not over use your vac when making shatter. Throwing the oil in the chamber and applying a full continuous vac,in the early stages of the purge is a form a agitation,and will most always begin to nucleate(wax)about 1.5 hours into the process.

Instead...
Put your scraped oil onto parchment using a putty knife,thin film is very important.

Place oil into your cold chamber, then turn on the heat. Pull muffins and let them fall,repeat until reaction slows.
My shatter runs have a minimum 36 hour purge time.
But I use very low temps 90*
And I just use my chamber as an oven, not much vaccing at all.
I do use it a lot at the end of the purge.

After the 36 hour low heat purge, it's time to remove the last bit of solvent and/or moisture out.
Turn up your temps to 117, once your oil has reached 117, pull vac for 20 minutes, let cool and flip the patty,when you flip; try to "stretch" the oil thinner, increasing the surface area, turn temps to 122 and vac for 15 more minutes, you should see bubbles popping RAPIDLY.
Turn off the pump,and release the vac,
Let your oil "rest" for 15minutes..

Or you can winterize. Super super smooth vapor. Yeeeaaah.
Edit: shatter stage first, then wax, comb later, if you get wax before shatter,something went wrong along the way
