0.5 mL K₃EDTA Polystyrene Blood Collection Tubes (9×44 mm) – 3K1130

Reliable Small-Volume Tubes with EDTA Anticoagulant

The 3K1130 tube is a 0.5 mL blood collection tube made of clear polystyrene, featuring a 9×44 mm external diameter. It contains K₃EDTA anticoagulant (~0.88 mg per tube) and comes with a pink, skirted screw cap. Designed for labs that need precise small-volume draws with consistent anticoagulation.

Key Features

• Volume: 0.5 mL — ideal for minimal-draw applications like paediatrics, micro assays, or when conserving sample volume is key.

• Anticoagulant: K₃EDTA — supplied with ~0.88 mg per tube, yielding ~1.75 mg EDTA per mL of blood. Wet droplet format helps enable immediate anticoagulation after collection; dried additive format is also available.

• Material: Polystyrene — gives good optical clarity for sample inspection.

• Dimensions: External 9×44 mm — compatible with EDTA racks and instruments requiring this standard size.

• Cap & Colour: Pink skirted screw cap (standard for EDTA tubes) — provides secure sealing and clear visual coding.

• Temperature Range: −4 °C to +60 °C — suitable for typical lab storage and transport.

• Centrifugation Rating (RCF): Up to ~1,500 g — safe for many routine centrifuge uses.

• Packaging: Packed in foam trays — helps protect tubes during handling and storage.
