Safe-T-Fill Capillary Blood Collection Tube 4,000xG Red Attached Cap 200 µL 50 Count

Package Count: 50.

Blood samples are drawn into the microtube through capillary action, reducing hemolysis, tissue contamination, and re-draws; no “scooping” or “milking” required.

• 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)
