2.0 mL Sodium Heparin Polystyrene Blood Collection Tubes (9×44 mm) – NH3130

Fast Plasma Tubes with Heparin Anticoagulant

The NH3130 tube is a 2.0 mL blood collection tube made from clear polystyrene, treated with 32 I.U. sodium heparin anticoagulant. It has external dimensions of 9×44 mm and is fitted with a white skirted screw cap. Designed for labs that require reliable plasma samples with quick preparation and standard handling.

Key Features

• Volume: 2.0 mL — suitable for many plasma assays without needing multiple tubes.

• Anticoagulant: Sodium heparin, 32 I.U. — fast acting for plasma separation.

• Material: Polystyrene — clear for easy visual quality checks.

• External Size: 9×44 mm — fits standard tube racks and centrifuge holders.

• Cap: White skirted screw cap — helps identify heparin tubes quickly.

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

• Centrifuge Rating (RCF): Up to ~1,500 × g — safe for standard plasma separation protocols.

• Packaging & Options: Available in packs of 100 / 500 / 1,000; custom filling or labelling available on request.

Why Choose NH3130 Tubes

• Ensures quick blood-to-plasma conversion for chemistry or clinical assays.

• Sodium heparin is less likely to interfere with many downstream tests.

• Clear walls make it easier to spot haemolysis, clotting or sample issues.

• Standardised white cap helps avoid confusion with EDTA or other anticoagulants.
