How do you flip when its so sticky? I have it on ptfe sheets and it is not flippable…

I had same issue with my first run … a friend said you just fold the ptfe or parchment over on itself and itll stick together allowing you to peel back one half of the parchment …

my first run, I think I made too thin a layer, so it was a nightmare to try and peel off. I ended up just leaving it for 3 days, with no flips … I guessed the layer being so thing that flipping was unnecessary … turned out well …

Try using a colder frozen tray under the slab for a few seconds/minute. that can help the wax to firm up on the back side, allowing you the ability to peel that paper from the wax, when you flip the slab.

Buy a pizza stone, keep in the freezer and when you need to flip stick it on there, parchment down. put another piece of parchment paper on top, flip it pull off the original like a band aid.

cheers will try that

You can also just put dry ice over the PTFE for a few seconds, flip, and band-aid tek. If you don’t have a cold stone/plate yet. Can also flip, chill, rip.

I’ll put a decent sized baking tray in freezer, should do … then do the band aid flip
Thanks

I fuckin gotchu right here man Purge Tips - Flipping slabs - YouTube

Edge it like a dollar bill face down on another parchment. It should come right off onto the clean parchment!!!

Honest to god if it weren’t for this video I’d still be freezing slabs and trying not to let it fall and break all over my freezer.

if I have a slab like that I will throw it in the freezer for a couple minutes and then place it upsidedown on a fresh piece of parchment paper and peel the old sheet off it. It will come off easily once you freeze it

This is how I learnt to flip slabs and been doing it ever since.

you didin’t dewax right ? fats usually darken when exposed to heat

I hear staging it on the begining is a good way to go. Basically go up to 15Hg let it sit for an hour pull 5Hg wait an hour, repeat untill at 29.9Hg. Then let it sit for 12-24 hours then flip every 12 hours

do you test your end product for solvents?
im interested in this technique but i dont like stopping the process.

Yes. you can achieve 0-300ppm very easily. The more flips te less solvent. In Washington, my extracts pass the solvent tests after 4-5 flips. So we can get a slab done in one day.

Could you please care to comment on how you achieve under 500ppm? Would be much appreciated. I’m concerned about residual solvent and purge for 4 days after BHO viscosity solvent release temperature is calibrated.
I have some stuff to be lab tested as I can’t bear the thought of making medication that has potential toxicity. I thought a 4 day at 40F MAX with flips 6-12 hour intervals after the initial 24 hour vac would be sufficient but I have my doubts. I would like to share in your personal standards with a degree of confidence without having to send everything for lab tests every time.

I agree with midsfactory on doing more flips. I flip my shatter 10 times over the course of 2 - 3 days and get 0 - 100 ppm consistently. Although, I think this tek works better if you have more than one shift extracting.

10 Flip Tek SOP

  1. Pour out solution into parchment/PTFE boat
  2. Let sit for 30min at ambient temps and atmosphere
  3. Pop into the oven at 100f to 115f, leave the slabs to sit for ~10 min to reach oven temp.
  4. Slowly pull vac, 5 inHg increments. (Allow the muffin to rise, close vac, let it crash, repeat until full vacuum is achieved)
  5. Once at full vac, leave it on continuous vac for 1 - 2 hours (depends on oven capacity, more slabs, more time.)
  6. After the allotted time, break vac slowly, and allow slab to melt flat ~15 - 30min.
  7. Take it out, flip, repeat until you’re at 10 flips. Mark a tally on the oven.
  8. Done.

If you’re using boats, right before the first flip, you’ll have to fold the shatter caked inner sides of the boat onto your slab, press down then rip like a bandaid to allow the excess scraps to adhere to the slab, then do your flip. But, if you know how to flip you probably already know this. :nerd_face:

I will admit, this SOP may be flawed in consideration to Midsfactory success with 5 flips in 1 day :stuck_out_tongue:

That’s basically our SOP! We just do eveything a little faster :slight_smile: I got 30 ppm on my last test.

Only thing we do different is the waiting around in the beginning. We pour it out and jam it in the oven. Maybe 5 min on the shelf before pulling vac. Watch the muffin, see if it’s going to grow into a problem. If it does, we usually break vac around -20(sea level) and let it settle. Then pull again and it’s usually fine.
Let the muffin settle, give it 40 min, pull her out and start flipping. Any folding is just cosmetic or to save space in oven. Thick slabs seem to purge just fine with enough flips!

@terplord420 I love your handle here . I get a chuckle everytime.

considering we stepped away from shatter for 5yrs lol, do you guys @midsfactory @terplord420 add slabs to an oven thats already been flipped, say slabs A-C are on there 4 flip and you have slabs D-F on flip 2, as long as theres no “muffin” anymore you can just keep all the slabs in the same oven(s) essentially an oven/2 for breaking muffins then a few to do the “flip purges”
