- Use these 100% plastic tubes to collect microliter volume capillary blood samples from finger and heel sticks
- They come preassembled with a capillary straw, attached pierceable cap and microtube to help improve the quality of capillary blood samples by reducing hemolysis, tissue contamination and clotting
- Hemolysis and tissue contamination are reduced by using capillary action to draw the blood sample into the microtube rather than trying to drop the blood into the microtube by over-squeezing (milking) or scooping
- Clotting is prevented by having anticoagulant in both the capillary straw as well as the microtube
- Green attached cap designates lithium heparin additive is the additive that is in both the capillary tube
- 10.8 x 46.6 mm
