Just a shot in the dark here...

Does anyone know of a vendor, preferably in the U.S., for sodium
polytungstate?  A short article by Krukowski (1988), who used it for
conodont separation, and a brief note in a 1990 SEG newsletter both mention
that it is patented by Sometu, in Berlin, the only vendor.  Is this still
the case?

Thanks for any help,

Steve
