And conversely we don’t know what you don’t know, so we have to ask…eg with the red hot nail.
if you look at the number of page reads vs the number of posts, one can absolutely conclude that it WILL be read by someone who DIDN’T know of cold starts.
Presumably we ALL started there…unless initially trained otherwise.
again, while it may not apply to you, it is also true that many just don’t know how to construct functional search queries.
Nor how important good ones are (or where until recently).
No way of knowing if that was the problem with out exploring right?
I went to home depot to get stuff to build a cold trap but didn’t search the effects of ethanol on brass/copper/nylon/vinyl until I got there and turned my ass right back around and came home. God I wish I had a rotovap right now. I bought a rosin press a long time ago and never used it so I sold it and wish I had spent that money on a rotovap instead.
I googled all the same things that I used to search here for coldtrap, and I’ve seen all those pictures and more, but what I’m still confused on is the length of tubing on the inlet/outlet. Can it just be 2 holes in the lid of something? Does 1 of the tubes have to sink to the bottom of the collection vessel? Do they both have to sink to the bottom?
I think you can answer those questions yourself if you think about it.
What are you trying to achieve? (Not drown your pump)
What was the coil I built about?
How did it help?
Why is stainless better than glass?
What are the commonalities and differences you’ve seen?
Tube length; explore pros and cons of inlet/outlet both high and low. Should be pretty obvious which is optimal if you’ve explored your goals and options.
Bubbling your vapor through any condensate, although quite effective for solvent recovery is probably not a great idea in a cold trap.
I have a little stonylabs lab pump now, gets to just under -23. So the hole going to the vac pump definitely shouldn’t be reaching the bottom of the vessel. I was thinking of coiling some tube at the bottom for the “vapor” and covering it with a little bit of ethanol to help with recovery. The most ethanol that I’d be working with at a time is 300-400ml. I’ll have to check back once I’ve built one.
Really? Well shit I just ordered stainless fittings and hose. I’d like to recover as much of this solvent as I can. So just drip it into a cup huh? Will the -22 be enough to do the final purge? I’d like to preserve as much of the terps as possible. I’m seeing people say go as high as 120f? Really? Right now I’ve got all the bulk of the solvent vaped off and it’s in my vac chamber at 32f.
I read a few of those yesterday. I was doing ethanol because I don’t have a closed loop but everything is pointing to butane just being better in every way. Fuck me…
Update on the flower qwet, ditched using the diaphragm pump to try to purge and hit it with full vac (or as low as my gauge showed, -29ish) and 34c. It’s not completely done yet but took a little taste test and it doesn’t taste bad anymore, and now that it’s not totally disgusting there is a discernable taste to it, it tastes almost chalky after the hit. Still doesn’t really taste like how it smells but I guess I’m going in the right direction.
My charcoal got here today and I have some winterized bho sitting in my freezer in solution so I decided to try to use it. Some of the charcoal was getting past my duda sheet around the edges because I couldn’t get it to seal properly. I got the .5um one and I noticed that one side has a ptfe coating and the other side is more “felty”. My first attempt was a massive failure because 1 I think I used too much charcoal and 2 in an attempt to get it to seal I cut way too big a piece. It still didn’t seal so I lost alot of what I was running to absorption. After a few tries I figured out that the sheets work best with the coated side down and I guess I’ll just have to do multiple runs to get all the charcoal out. I’m not expecting this open blasted stuff to be any good, but I figure I should learn the process with the crappy stuff before going anywhere near any good stuff.
I would be posting pictures along the way for visual aids because that’s way better than huge bricks of text but any pictures could give people clues as to where I live and I don’t want that.
Figured you guys would get a kick out of this. My acrylic vac lid cracked. I knew this was going to happen, I didn’t realize how quickly it would happen though. I figured I’d get at least 1 or 2 purges of ethanol before it gave way but nope. Literally less than an hour and it started cracking. I’ve got a glass lid on the way. Hopefully the gasket and hardware fits.
Where did I say it was the lids fault? Ethanol does that to acrylic. Maybe you shouldn’t be on the Internet since you don’t know how to not be a prick.
