Product Overview
This 9ml purple cap EDTA K2 tube for test features a purple cap and is internally coated with dip-sprayed potassium ethylenediaminetetraacetic acid (K₂ EDTA). It is ideal for routine hematology tests, blood typing, cross-matching, and molecular diagnostics. The anticoagulant preserves the integrity of whole blood samples without clotting.
Key Features
-
Accurate Anticoagulation: K₂ EDTA effectively chelates calcium ions in blood, instantly preventing coagulation.
-
Uniform Coating: Advanced spraying technology ensures even distribution of anticoagulant, reducing the risk of hemolysis.
-
Clear Tube Body: Made from PET or crystal glass, offering excellent visibility for easy sample inspection.
-
Consistent Vacuum Accuracy: Each tube is vacuum-calibrated for accurate blood volume, enhancing sample reliability.
-
Secure Closure: The purple cap seals tightly to prevent leakage and contamination.
-
Durable Labeling: Customizable labels are waterproof and writable, suitable for barcode or manual identification.
