Product description

Buffered Sodium Citrate is used in clinical laboratories and blood banks as an effective anti-coagulant, usually in a ratio of 1:9 sodium citrate/blood. The citrate ion chelates calcium ions in the blood by forming calcium citrate complexes and disrupting the blood clotting mechanism.

Medicago’s Buffered Sodium Citrate is supplied at two sizes with pouches giving 100 ml or 1000 ml of 3.2 %, 0.109 M buffered sodium citrate solution.
