• Capillary straw and microtube are coated with anticoagulant Lithium Heparin (Green 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
• Available in a variety of sizes and draw volumes, with or without gel separator
