Übersicht

Potassium phosphate tribasic is a reagent with a very high buffering capacity. It is widely used in molecular biology, biochemistry, and chromatography, used for the extraction of keratohyalin protein from bovine tissue, to study the effects of freezing and thawing on the stability of proteins sensitive to conformational changes. It is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent.

Häufig gestellte Fragen

What does AR mean?

AR is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. AR is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.

How should this product be stored?

Store in a cool place, desiccated, under argon. It is supplied under an argon blanket; reseal under inert gas after each use.
