• Blood samples are drawn into the microtube through capillary action, reducing hemolysis, tissue contamination, and re-draws; No "scooping" or "milking" required

• 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 whole blood hematology (haematology) determinations
• Self-sealing tube automatically "re-seals" the cap after piercing (not made with natural rubber latex)
