When I got mine I said the same thing “I’m only ever going to run a qp at a time” hahaha that didn’t last long. I fill my 30# tank with 3 lbs of butane using a can tap tool and inject the entire tank into my extractor. I only fill it with what I need.. if you wanted to keep extra in there you could always use a refrigerant scale( you should have one anyway)
... when sizing your collection pot to your column make sure you have 3 column volumes of space at only 80% capacity on your collection pot. You’ll notice they only size there’s for 2 column volumes.
Use only high pressure clamps
Get an immersion circulator for your hot water bath recovery
Get an 8’ solvent hose from your recovery tank to your extractor you’ll thank your self later
Oh and always build a bigger collection pot then you need because you can easily just add different column to it down the road it’s much easier then building another unit a few months down the road
... I would personally buy some liquid nitrogen and test for leaks, cause its high pressure none flammable. Hearing way too many horror stories even in this day and age from too much carelessness. .. .[/QUOTE
Nice glad to hear itFrankie2 had his first run this afternoon. I was pleased with how all parts performed except for the top 8" clamp which lost pressure at 20 psi. I tightened the clamp as tight as possible and still could not get the leak to stop. I will probably have to purchase the "PRO" version of the clamp. These are supposed to be machined to a tight tolerance. I did a visual of the gasket and it seemed to be fine. I saw no pits or gashes on either surfaces. During deconstruction i was particularly careful to look for debris on either side as well.
the bottom clamp did not fail. When placed in the warm-water recover pot, there were no bubbles from the bottom 8" clamp or from the 4" splatter platter clamp.
Using the warm-water pot to hold the supply worked like a charm. The warm-water bath forced the increased pressure and thus the gasket failure. M
Sounds like my next purchase will be a bottle of nitrogen & a regulator for pressure testing....

View attachment 825328 Part 1 get one of these for under your extractor while in the water bath it will allow hot water to flow all around the collection pot and keep a stable Temperature and won’t allow cold spots to form.
Roger that!
Part 2
Why do you have what looks like a hemisphericle reducer on the bottom of your collection pot that has a 1.5 triclamp?
Added vacuum?? I don’t follow? You mean more volume?
I’d imagine that extractor is quite unstable when fully assembled I would construct some some of rack to hold that thing up.

Your actually thinking about that backwards you want the extractor to stay put and you want a platform for the water/dry ice bath to move up and down on. Leave the extractor where it is and move the buckets basicallySpeaking of racks. I have been trying to find one that allows the tanks/spools to be secured to a vertical track via clamps much like a drawer slider except in the vertical aspect. I would like to be able to slide the unit up; slide out a bucket/cooler and put another in its place and lower the attached unit. I saw that setup in a video and have been trying to find a mfg. since.
Sweetleaf systems use something similar to this extrusion for their racks... The T-nut allows the sliding action in the grooves of the extrusion. You can see it in action in some of Bret Mavericks youtube videos where he's running the v3 setup.
