Not quite sure how well they work, there isn't much surface area on the inside of the chamber.
Can't say I don't want to buy one though! I believe SkyHighler posted this link, and I got really stoked. I just doubt its abilities without the use of a coil to help condense vapor into liquid.
I'm sure some other awesome cheap finds will be coming out the more the market grows
I swear you are following me from thread to thread, think we have the same tastes...

we will see how it runs.
A coldfinger stuck in a Dewar (or Thermos) of LN2 might be all you need.
Here's a professional model for the low low price of 1k.
Dry ice / isopropanol cold trap. Provides pre-pump protection by condensing vapors. Vapors contact outside stainless steel shell, traps up to 1.5 l condensate. Large, removable center well accommodates up to 2.8 l of dry ice / IPA slurry for up to 12 hours protection depending upon vapor load.
It might run better just with much shorter hose.
I am evaporating off and buying so much ethanol.
Couple questions, can I use a rotary vane pump still? If so should I worry about pump oil being in my reclaimed ethanol(gin)? From oil molecules backstreaming? I will throttle the pump to increase contact time and bleed atmosphere slowly to try and help prevent this but I still worry.
IDK your application, what you're doing, so, IDK anything about anything really. In standard use IDK about this throttling you mention. The only problems I've had with pump oil coming back were solved by loosening the connection at the pump while it was running, before shutting down. You should get a ebay or labx rotavap and distill that ethanol anyways.
This is not a substitute for distillation. If you have a lot of vapor and a puny rotary vane pump that's getting hot because you're only down to 20 mm, you need a diaphragm pump, better solvent stripping, or a bigger pump instead of a better trap, even though the trap will help with lowering pressure.
I winterize all of my bho, then evaporate it off at room temp on ptfe, then purge in an oven into slabs of shatter. I don't need a cold trap for distillation, I need one for reclaim and reuse of my solvent.
