Description
- 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 (red cap) to facilitate 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 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)
