What industries use %10 NBF (formilin)that could benifit from the use
of a powdered formilin that could be mixed into 10% NBF in tap water.
Eliminating a large amount of shipping costs.

You realize that powdered formalin is already readily used and
available. Myself, I prefer it premixed (or in liquid concentrate) to
avoid exposure to the powder. It is worth the extra ship costs;.

I do belive that you are talking about the product that my company has
produced and is actively suppling the Histology market. If so the
question is intended to find other markets that are either using the
formalin specifically or that the are using formaldahyde at solution
of less than 8% formaldahyde for what ever reasons.
