Hello,
I saw this posted on RADSAFE:

DuPont Pharma sells sources like these.  For more info please contact
Cheryl White (1-800-225-1572 Ext.8763).
I spoke to Cheryl briefly. She said that for an academic application, as
suggested, this may be a bit expensive. **But** she also said she knows of
a company which specializes in sources exactly for the type of application
as described.

(Next week I'm going to introduce Cheryl to Internet - so soon she'll be 
available here too.) 

Regards, 
Charly                     ott@wmvx.dnet.dupont.com
