General summary of the situation as I understand it: Copper is considered incompatible, although it doesn't seem to be extremely catalytic at ambient temperatures and lower. Pure aluminum is considered the best; 6061 aluminum alloy isn't bad; stainless is OK; ordinary steel tends to catalyze it easily (especially if rusty). With nonmetals, polyethylene tubing and containers should be OK (especially at ambient temp. and colder): Viton (and probably also EPDM) O-rings should be good. Nylon deteriorates rather rapidly; vinyl and urethane may have problems; fluoroplastics (PTFE, FEP, PFA, etc.) should be good. -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
