A. Unfortunately haven’t had enough to fill halfway. Last run, filled 1L flask 1/4 of the way full. Very slow distillation.
B. Yeah, lots of reflux
C. I typically collect main body around 200-205C mantle temp and 164-169C vapor temp. Is it just a case of my mantle being set too low? Only insulating with tin foil while I wait for fiberglass rope order to ship.
Yes in that case insulation of flask and head is very important
You should also raise your mantel temp a bit
Reflux is condensation before it should
Some reflux is good but like a drop a second
Thanks for your help! Typically my vac depths are 210-200 micron for main body on first pass and 90-100 for main body on second pass. At those depths, what vapor temperature range should I be collecting mains? Knowing about how high I can take the vapor temperature would help me be more comfortable increasing mantle temp.
At 200 mic your vapor will be around 210-230C
At 80 mic your vapor at 185-205C
For thc
For cbd it s about 5 higher
Mantel about 15C higher on cow
10C higher on hot Con
Huh really? This confuses me. I just distilled 228g of decarbed, ethanol (-80C) extracted crude and collected a mains fraction that totaled 140g at 210 micron, vapor temp. 166-169C, and mantle temp. between 200-209C. This distillation took like 14-16 hours start to finish. So something is clearly wrong.
Your temp ramping
Is diffrent not wrong let s say it that way
Any compound to vaporize needs a certain amount of heat
That amount is static always the same
If you ad heat but the compound doesn t make it treu in vapor form to the condensor but reefluxes. Back
The same amount of heat needs to be given again. Until it passes treu
So Yes you can distill at a low mantel temp
But by adding more heat the compound will more likely. Pass the head
Do you mean 210-230C mantle temp at 200 micron? For 210-230 vapor temp, wouldn’t the mantle be up past 250C? Is that not too hot?
The law of boiling
Since a certain amount of heat is nesseray to boil and a certain amount if heat is nessesary to vaporize
The temp of the mantel only Dictates the time in wich this heat is absorbed by the boiling compound
Or administered to the compound
No matter How much heat you trow at a compound not Until all has vaporized will the temp in the crude rise for that
Specific compound to boil off
So mantel temp is your trothel !!
Could I use this pump with chilling fluid and dry ice to chill a rotovape if needed, or a jacketed stainless part?
I wouldn’t use dry ice in the chilling fluid, but you could put a coil inline and use that.
If you are in an adequate ventilated area, why not use isopropyl instead. It’s much cheaper
Honestly that is pretty much those shitty SPDs do. You have everything dialed as well as you can. I have 3 of these POS in different sizes and they all take 12 hours to move everything over. Doesn’t matter which pump I use. Best way to get better speeds is larger bore glass. Not just the vac lines, but the ID of all vapor paths.
Looks good anyway bruv.
6hrs for a 900ml run for me. 100% china glass and mantle.
I can get it down faster, but I like to take my time.
That’s a joke correct ? 6 hr for 900ml? On a cheep China rig (not full bore) 2l system with a cheep harbor freight pump it only takes 1hr do distill 1000ml or so. So how are those times ok with you? Or is this a troll post ?
Your not doing somthing correct if those times are normal for you?
So your getting over 16ml a min? I get 6-9 a min on a 5l at under 50 micron for 1st and 20 for 2nd all full 1”. Those are crazy fast speeds, and at what temps and whats your potency like
Can anyone who uses 24/40 glass (not full bore) comment on what distillation speed you get? What cfm pump are you using?
On a 2 liter China rig once vacuum is right and oil is heated to 120C and dead calm in the flask 1.2 L volume crude
3.15 hours last drop of tails
On 5 liter 3L in bf crude 6 hours
Never tryied a 10 L without full bore.
On my 2L rig it takes about 12h to distill 1-1.2L of crude if starting material wasn’t decarbed or around 8 with decarbed.
When I try to speed the process up decomposition and side reactions are entering the chat.
I usess springs in my head to help with separation. It adds 1-2h to the run but the distillate has less pigments in it. My goal was to help with CBD/THC separation and it kinda works but not in the way I expected it to work.
You guys can all rush thru it and do 2 passes fast as shit.
I go slow and ramp up temps. I pull +93% thc light yellow 1st pass every time. Sub 70 microns.
So either I do it correctly, or?.. 13 runs under my belt. I’m banging out a 2l run tomorrow. I’ll time it and post it.
Small detail deu to my very torough sop of pre Distillation i start with 70% tac crude so my heads are less than 100 ml and my tails slightly more
My overall tac is for mains low 90%
I am a commercial producer in the land of the blind so i get away with medium quality
