General Manufacturing Information
Textiles, apparel, and leather manufacturing
1,2,3-Propanetricarboxylic acid, 2-hydroxy-, sodium salt (1:2): ACTIVE
ANTICOAGULANT...IN SOLN WITH GLUCOSE TO PREVENT CLOTTING OF BLOOD INTENDED FOR TRANSFUSION. PREFERABLE TO SODIUM CITRATE, SINCE IT PREVENTS CARAMELIZATION OF GLUCOSE ON STERILIZATION BECAUSE OF ITS ACIDITY. SUITABLE SOLN CONTAINS 1.7 TO 2% & 2.5% DEXTROSE; 120 ML OF THIS SOLN PREVENTS CLOTTING OF 420 ML BLOOD.
