[RASMB] fluorochemicals

Dear Carlos,

you could use Fluorinert FC-40 (Sigma F-9755) or Fluorinert FC-77 (Fluka 47090).

Best regards,

Arne

Dear RASMB members,

I am planing to do several sedimentation equilibrium experiments with fluorochemical (Beckman 306394) at the bottom of the cell, to raise the sample column with an inert chemical. 
My Spanish Beckman dealer says that nowadays, this product is not in Beckman products list. Do you know the chemical composition of this product and if it should be able to get it from another Company. Could I use another product?

Thank you in advance for your help,


Carlos
