Hemi lid is very important it creates a vortex so tour gas doesnt find the path of keast resistance and it “recycles” its self theu the beads to ensure all vapor touches the beads.

Idk about using silicone, PTFE envelope , PTFE only for me, maybe viton up top
It’s almost like those cheap sight glasses bestvaluevacs makes, why the f*** are they even offered on an extractor

No! No! No!
Do not use silicone with hydrocarbons.
Unless you’re looking to make up for the lack of a PRV.
Had a major manufacturer ship a rig with a couple of silicone gaskets in it. Pulled parts of them out of the filter after the first solvent run through.
Explained the leaks that hadn’t shown up with 200psi nitrogen…
Silicone gets a D with Butane.
(D =Severe effect; not recommended)

Put coffee filter at each end
rather use the silicone cause i get great results so far using the 5 micron gasket , until there’s a5 micron ptfe gasket i ain’t messing up my flow with coffee filters. been there too long with the closed column.
We are talking about sieve here right? Not material?
Sieve is gas only, ur heating ur collection and turning the liquid to gas. Then send the GAS through the sieve
I say put one or 2 coffee filters at each side (unbleach) bc the sieve is clay beads, they have dust on them, not only will pointing the flow up help prevent the dust from getting into your gas , but the coffee filters are a last defense.
REMEMBER, you don’t break you sieve column down but to regenerate your beads, so this coffee filter as last step is just to help.
U don’t wanna slow down RECOVER either w 2 - 5um filters, you would bogged down!
I may have posted the wrong one after u asked for a 2500, I was just looking for what u asked not thinking about what was needed
For gas , not liquid, the sieve I’m sure, this is better for RECOVER…w speed …the first one will work I sent but slow u down …I may be wrong but I don’t think so
Injection you need 5um u want sinstered disk or filter plates w 5um paper
