Thank you very much.
Oh, this glass column is called “Chromatography Column”, first time to know.
We can help
They’re marketing it as such but nothing makes this unique to chromatography. It is, however, large enough perform a number of purification methods on at least 300g at a time per column. How much are they trying to charge for this glassware?
this is a really nice channel. Thx!!
They are charging for $9500 per column. Is this too expensive?
I think you can find it for a few thousand cheaper – they’re really using “chromatography” to mark it up.
that is true. I could find a glass blower to make it. It is just a straight pipe
what is expensive is the sillica inside
Iv got 5.5ft x 24" wide coulmns i use to rememove thc, iv got them built personally. i paid with stand 5000.00.
My 6x48 can do 1.5 kg easy depending on the pesticide.
Not every pesticide is easy to do. Anyone done these with c-18 reverse phase?
@Krative, this is essentially the equipment I was discussing. I think the actual picture I’d mentioned may have been @Thedistillator’s setup he’d posted in a thread somewhere on here.
you using stainless spools?
Im probably gonna go ahead and get a bunch of 12" diameter spools and fill em up with adsorbents before running 10 kilos of crude through
Me and @CBNight have been looking into the cost of c-18 reverse phase silica and the stuff is expensive. That is the real cost like @qma said.
Recently, ive been talking to a few companies trying to get my Silica Gel 60a price down. All of them carry c-18 but its so expensive its kinda scared us away from playing yet till we see some other member do it.
No. Just standard research gravity column. I pick my pesticides carefully so I just run the easy ones or very low amounts of the others. A few Cat 1’s that concentrate in extracts are the most difficult things I’ll do.
With a stainless steel column, could you use temperature to judge when different fractions elute?
TLC is the classic technique
I just found out there are actually a stainless version of this column. It is call HPLC. It is basically a stainless steel column hock up with a lot of spectrum that monitoring the solution. I saw a small one on the trade show. Will send out picture soon. It will cost around 50,000 per unit. That one can bring potency up to 99.9% CBD
this component can be made much cheaper than 50,000
Only need a thermometer probe. All of the collection may be done with tubes on a conveyor or on a 2 axis cnc platform. Cheaper spectral imaging designing here
