Trevor,
here is the product reference:
http://www.scharlau.com/TDS/AM0276_TDS.pdf
Not sure why they moist the Am. dichromate (0.5% - 3 water) but this is a
pure reagent for analysis and it will probably be expensive. Are you sure
that a cheaper, technical grade product, is not enough for your
(photographic, I assume) purposes?
