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 a clotting activator to facilitate clotting.
Attached cap is color-coded red 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 light-sensitive serum determinations in chemistry
Gel separator serves as a barrier between blood and serum after centrifugation.
Amber microtube ensures light-sensitive sample integrity providing protection for testing (e.g. bilirubin).
