Designed for use in the examination of coagulation parameters, coagulation tubes contain a buffered tri-sodium citrate solution. Citrate concentrations of either 3.2% (0.109M) or 3.8% (0.129M) are available, with a mixing ratio of one part citrate to nine parts blood.

•  VACUETTE® tubes are manufactured from virtually unbreakable PET plastic
•  These clear tubes are supplied with blue non-ridged pull caps that feature an exterior color-coded ring to indicate the draw volume.
