FC-43

Hi all. We were recently trying to purchase FC-43 directly from 3M only to find it on
backorder and (too large) minimum volume requirements. I see the Sigma catalogue
product Fluorinert FC-43 (Cat # H5262). I presume that to be the same material. Anybody
who has used it - are you finding acceptable sedimentation equilibrium data?

Best regards, Don
