[labnetwork] Trifluoromethane CHF3Supply

[DeRose, Guy A.]

Hi James,

We also use Advanced Specialty Gases from Reno, Nevada when other vendors are back-ordered and they are very reasonably priced and usually have stock within a couple of days.  Shipping to Scotland could be slower and probably expensive, but it doesn’t hurt to ask.

FYI,
Guy

Hi James,

My facility purchased two cylinders back in Sept/Oct (both in use, sorry!) from Advanced Specialty Gases, and I don’t recall the lead time being longer than a few weeks.  ASG claims they ship worldwide – might be worth inquiring.
