Safe-T-Fill® Capillary Blood Collection Tube Whole Blood Tube K2 EDTA Additive 1.1 mm Diameter 125 µL Purple Pierceable Attached Cap Plastic Tube

100% plastic tubes collect microliter volume capillary blood samples from finger and heel sticks

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

Capillary straw and microtube are coated with anticoagulant Dipotassium (K2) EDTA (Purple 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 whole blood hematology (haematology) determinations
