Seems like you would design an experiment so tilting gets the mixing actions
you want, then put in fridge or freezer to cool, then open and decant your extraction.

perhaps some 3D printed shape in ABS would help with that step and be fairly
clean, and recyclable, letting you use a new clean one for different types
of chromatography runs.

Maybe 3D printing is too leaky, but machined plastic with a window
installed by o-rings could be a good extraction or reaction chamber.

Did you read about the chemists making one shot 3DPrinted reaction chambers?

They 3D print "made from a quick-drying silicone polymer usually used as
a bathroom sealant to build the vessel up layer by layer."

If your idea won't work with silicones, maybe 3DP of polypropylene
could be done in a messy strings-of-plastic-stretching-around way
to get glass windows embedded and ports, and such. With polypropylene,
you can heat a metal fitting and press it into an undersize drilled hole
and it will make a strong connection if the metal has some
ridges to grab on.

If you like the re-usability of glass, I have some old pyrex for sale.

Wouldn't the CO2 boil/explode the second I open
