0.5 mL Wet K₃EDTA Polystyrene Blood Collection Tubes (9×44 mm) – 3K1130W

Blood Tubes Ready-to-Use for Immediate Anticoagulation

The 3K1130W is a 0.5 mL blood collection tube pre-loaded with wet K₃EDTA anticoagulant. It features a 9×44 mm exterior size, constructed in clear polystyrene. The wet (liquid) additive ensures immediate mixture with blood upon draw—ideal for labs requiring fast, accurate anticoagulation, especially in haematology or diagnostic settings.

Key Features

• Volume: 0.5 mL — well suited for small volume collections (paediatric draws, micro-assays).

• Anticoagulant Type: K₃EDTA (wet) — provides instant anticoagulation, reducing potential delays or variation introduced by mixing.

• Material: Polystyrene — clear transparency for easy visual inspection.

• Size: 9×44 mm (external) — compatible with standard EDTA tube racks, centrifuge rotor holders, or diagnostic analyzers.

• Colour-coded Cap: Pink skirted screw cap standard for EDTA tubes, enabling quick identification.

• Temperature and Handling: Suitable for typical laboratory conditions; follow guidelines for storage and avoid extreme heat or prolonged freezing to maintain wet additive integrity.

• Centrifugation: Safe under normal blood separation forces; ensure tubes are balanced and follow lab-specific RCF limits.

• Packaging: Bulk pack options for efficient supply; stored and transported with care to prevent leakage or additive loss.

Why Choose Wet K₃EDTA?

• Wet EDTA means the anticoagulant is in liquid form already in the tube — less risk of inconsistent mixing.

• Faster sample preparation; glove-side readiness helps reduce pre-analytical error.

• Particularly helpful when working with small draws where correct anticoagulant ratio matters.

• Great for clinical settings where speed and consistency in blood sample handling are priorities.

Typical Applications

• Full blood count, white cell differential, haemogram, morphology

• Clinical diagnostic labs and emergency settings

• Child/infant blood sampling where volume is limited

• Research projects with many small-volume draws

• Environments where sample timing, anticoagulation consistency and handling speed matter
