Product Description

Sodium Phosphate Dibasic

Application Notes

Sodium Phosphate Dibasic Anhydrous is used as sequestrant, emulsifier and buffer in foods, as mordant in dyeing, for weighting silk, in tanning, in manufacture of enamels, ceramics, detergents, boiler compds; as fireproofing agent, in soldering and brazing instead of borax; as reagent and buffer in analytical chemistry, cathartic, laxative. Useful in conjunction with Sodium Phosphate Monobasic in the preparation of biological buffers. Used in many applications including the purification of antibodies.
