These plasma tubes work well for pediatrics and neonates
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.
Capillary straw and microtube are coated with anticoagulant dipotassium (K2) EDTA to prevent clotting.
Attached, pierceable cap is color-coded green 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.
