General description

Potassium sodium tartrate tetrahydrate is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient.

Application

Potassium sodium tartrate tetrahydrate has been used in the preparation of Lowry Reagent for the determination of microsomal protein concentration in rat hepatic microsomes by Lowry method. It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) Reagent and Fehling′s solution B, which are used in the determination of reducing sugar.
