Potassium dichromate, 99%, Thermo Scientific Chemicals
Description
Potassium dichromate is most often used as an oxidizing agent in laboratories and industries. It is used as a precursor to prepare potassium chrome alum which finds application in leather finishing and tanning. It is utilized in the preparation of chromic acid for cleaning glassware and etching materials. It is an active ingredient in cement used for retards setting and improves its density and texture. Furthermore, it is used in photography and in photographic screen printing. It is also used in wet test analysis as an analytical lab reagent and in ethanol determination.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
