For small sample volumes and optimal instrument compatibility, plastic blood gas capillaries are available in a variety of sizes and volumes.

• For capillary blood gas analysis with range of volumes
• Preparation: Calcium-balanced lithium heparin in droplet form as a spray dose; 80 IU heparin/ml blood
• Calcium (Ca²⁺) balanced heparin is also suitable for determining electrolytes
• Low gas permeable PET is flexible and robust

Blood gas capillaries provide reliable measurement results with a special calcium-balanced heparin coating. Break-resistant PET plastic ensures maximum safety during collection. The special surface treatment enables quick filling of the capillary, making sample collection easier and reducing the risk of coagulation.
