RAM Scientific | Capillary Action Blood Collection Blood Gas

Do you still scoop?

Scooping increases the risk of hemolysis, tissue contamination and clotting – it's also just plain messy. SAFE-T-FILL® collection tubes use capillary action to draw the blood into the capillary straw where it is immediately mixed with anti-coagulant. Discard the straw, pop on the attached cap, and your sample is ready for analysis.
