VACUETTE® tubes contain sodium citrate solutions in concentrations of 3,2% or 3,8% and are used for assays in haemostaseology. The mixing of 9 parts blood to 1 part sodium citrate takes place immediately after the blood is drawn by inverting the tube, causing anticoagulation through the binding of calcium.
