I’m not as cheap as $65 plus tax but I’m $115 shipped anywhere in the lower 48 for a 20kg box from carbon chemistry

Cheap insulated bucket for catching terps/solvent during spd and not making a mess with condensation.
I got the containers from a food/resturant supply store and the foam from extra packaging i got in the mail.
It keeps the dry ice bath cold for a full 8 hour run. It only builds condensationas far as the outside of the second SS bucket and all collects in the clear container. You can easily just take the first bucket out(containing the dry ice/alcohol) then dump out the collected condensation.

That’s actually what I wanted to do but I couldn’t find the diameter pvc I needed in store. I would have had to order online or call around and I didn’t want to wait.
Fucking excellent idea man. I love it
Be sure to tac a screw in it so it doesn’t bust open mid run.

Thanks man! I just gorilla taped the seam but a few sheet metal screws would definitely be the move!

In the Lab - Chemical Free Glass Cleanup
Cleaning d8 & pine tar thick distillate crap off glass:
cheapest oil sold at walmart (any kind)
granulated sugar as abrasive
toss oil in while everything’s still warm but works great cold too
if you toss the oil in while the glass is still hot/warm you can dissolve (?) the distillate/concentrate into the oil and at 50% or greater concentrate to oil, you then simply dump the jiz oil and wash
get that cheap oil all over every spec of tar
you can toss in some sugar (as abrasive) when you apply the elbow grease
use an abrasive pad; once tar is off dishwashing detergent - rinse - done
I like to dump in trash the jiz oil - not wash into drain as you may be roto-rootering the same solidified crap from your clogged drains later
no gnarly chemicals to inhale during daily cleanup
thinking about a dedicated oil cleanup station

stop dragging kegs around your lab. use wheels.
I like these 16in plant dollies.
$25 from home despot. probably available cheaper elsewhere.
Work great for moving plants around too

I can attest that this particular model fits kegs almost perfectly!

Easiest decarb test ever…
Dissolve a small sample in EtOH, dab on a TLC plate with a capillary tube and allow to fully dry (careful using a heat gun-you may decarb your sample!) apply bromocresol green ( I use a soaked q-tip in a rolling fashion) Yellow? keep going. Blue? Yer good to go!
I used to run a TLC plate in a chamber with Ethyl acetate and Heptane …but why bother!

Is there an SOP for TLC floating around somewhere? I’ve been meaning to buy a kit but I’d like to understand what I’m getting in to first

I have a “Black Hole” toner cleaning station at my print shop. Works perfect for bagging up powders and not getting it everywhere. I picked it up used years ago for $300.

Hey how dis that valve on the bottom work? Just got a bunch but i hate the blue handle ones so just curious before i swap some others out for them
It’s crap, I replaced em with swagelok knockoffs actually. They held ok for a year, then the nut packing started leaking and I couldn’t get the inner part to break loose, or tighten for that matter.
They knockoffs seem ok, except the port on em is only as big as an jic opening.
Ya about what i figured, glad i didn’t pay for them. Which swage knock off, i got a bunch of superlok ones jm about to use
Definitely a good thing you didn’t get those ones, and the knockoffs I grabbed off of ebay.
Edit: they ain’t nearly as good as the superlok’s I assume.

I love this thread! I’m excited to try the tamponTek soon…along with a few others. Thank you all for what you’re doing!
I got a few #4 filter bag housings a while back hoping they would be able to get me down to sub micron. After all, “they” sell those welded ptfe coated bags right?
Turns out there was no way to actually get a seal between the basket and housing Or the bag and basket. It did well enough to rough filter but I was getting a ton of powders/sediment.
I’m sure other filter bag setups have this sort of thing built in…
O-Rings FTW

If you’re looking for a cheap option to rack mount your system check out network data racks. They’re made to hold the weight and you can find them for $80-200.
