  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.
