Has anyone used the QSP CRC column with the QSP 2 lbs loop? I would imagine the crc would just go in between the column and the recovery tank, has anyone tried this?
Yes its been done before
I stopped becuase it made the loop insanely tall and I ended up getting a rack instead

I’ve not used that specific one. If you are looking at the 6" CRC column on a 2 lb extractor, I’d say that is oversized for the extractor…
The CRC column an intermediate step in between the material column and the recovery tank.

Pack your powder at the bottom of the biomass in the material column. Fuck the crc

Yea spend that money on a 5 micron filter plate and a 0.5 micron filter

Right on. I suggest using a bypass tank between material column and crc. You want to get everything off the weed fast and the crc can get in the way of that happening

Is there a way to do that with the QSP unit?
Use a second spool you can inject into the top cap with & run the bottom end to the crc to give you room for a flood column between material chamber & qsp crc that way you can equalize your pressure & flow rate.
Don’t pack the bottom of your column. A 4" 2lb column packed with tree, papers, and powders is goin gto be a fucking bitch. Guranteed flow issues.
Running cold CRC you would want to have a thinner column to help save on powder, however the surface area and thickness of your cake determine effeciency. I prefer to use the 6" QSP CRC. I do use a bizzybee disc inside my column.
Also, you don’t really need a flood column on your machine. I think people make way bigger deal out residence time then they should. I typically run a no soak SOP and it takes 9 minutes to remove all the gas from my flooded material column. And just about 25 minutes for the full run. I run 70/30 10lbs/lb and I recover with a 2 cylinder BVV rebuild cmep and a DI tank at 2psi.

It’s only gonna have flow issues when you start to have a massive cake. 450g+ He should be able to run 50-100g of powder no issue whatsoever. I solely run like that and don’t see flow issues

I’ve been able to reduce n2 use and run time, just by running a nice big CRC column with a wider surface area apposed to deeper. Consistently deal with flow issues steming from material and filter on the same column. There are also a bunch of other SOP issues that present using a single column for both that just slow you down.
If your just doing a few lbs a day I guess it’s no big deal, but if your trying to feed the machine 20 socks a day it’s probably not the best bet.
There is more than one way to skin a cop, and different ways work for different people with different ends in mind.
Personally I do 6 socks and then run that solvent thru the crc at one time(batch-style)… it’s all depending on what you have on hand and what you’re trying to do.

This is very different from what we’re talking about above, he’s running small columns not 20 socks a day. I’m suggesting compressing the media under the bio. Not just an attached crc that’s compressed under vacuum
