Pre-assembled with a capillary straw, attached pierceable cap, and a microtube
100% plastic tubes collect microliter volume capillary blood samples from finger and heel sticks
Blood samples are drawn into the microtube through capillary action, reducing hemolysis, tissue contamination, and re-draws; No "scooping" or "milking" required
Capillary straw and microtube are coated with anticoagulant Dipotassium (K2) EDTA (Purple cap) to prevent clotting
Attached cap is color-coded to designate the type of additive that is in both the capillary tube and the microtube
Lot Number, Expiration Date, and fill lines are printed directly on the microtube
A complete end-to-end fill of the capillary straw accurately measures the stated fill volume
For plasma determinations in chemistry
Small sample sizes, great for pediatrics and neonates
Available in a variety of sizes and draw volumes, with or without gel separator
