Potassium Bromide Powder Lab Grade 99+% Purity

Potassium bromide is a white crystalline salt supplied as a lab grade powder at 99+% purity in a 250 gram quantity. It is highly water soluble and stable in storage.

In darkroom photography it is the standard restrainer in developer formulas, holding back fog and controlling image tone, and it appears in bleach and toning baths. In the laboratory it is used as a bromide source in synthesis, as a supporting electrolyte, and in pressed pellet form as a matrix for infrared spectroscopy. It also has an established role as an anticonvulsant in veterinary medicine.
