The "old" Nytran is still available, only under a different name. It
was (and is) manufactured by Micron Seperations Inc. of Massachusets
(Westboro?). Untill 1990 they sold to S&S which marketted the membrane
as Nytran. Now it is called Magna NT and can be bought from MSI
directly. Sorry, don't have the phone number handy, e-mail me if you
can't get it from directory information. BTW, we still think its the
most sensitive thing going.
