5.0 mL Sodium Heparin Polystyrene Blood Collection Tubes (15×54 mm) – NH6740

Reliable Heparin Tubes for Moderate-Volume Plasma Collection

The NH6740 tube is a 5.0 mL blood collection tube made from clear polystyrene, treated with 80 I.U. sodium heparin anticoagulant. It has external dimensions of 15×54 mm, and comes fitted with a white screw cap. Designed for labs needing moderate sample volumes with rapid plasma separation and reliable heparin performance.

Key Features

• Volume: 5.0 mL — ample for many chemistry or plasma-based assays without needing multiple draws.

• Anticoagulant: 80 I.U. sodium heparin — helps prevent clotting quickly, ideal for plasma preparation.

• Material: Polystyrene — clear, rigid walls allow visual inspection of samples.

• Dimensions: 15×54 mm external — compatible with standard tube racks and centrifuge holders.

• Cap & Colour: White screw cap — easy visual identification distinguishing heparin tubes.

• Temperature Range: −4 °C to +60 °C — safe for typical lab storage, transport, and handling conditions.

• Centrifuge Rating (RCF): Up to ~1,500 × g — reliable for routine separation of plasma.

• Packaging Options: Supplied in bulk (100 / 500 / 1,000 units) for lab-scale supply.

Why Choose NH6740 Tubes

• Provides enough sample volume for moderate throughput without over-draws.

• Heparin anticoagulant is suitable for many chemistry and diagnostic assays where EDTA or citrate may interfere.

• Clear polystyrene allows early visual detection of issues like clotting or haemolysis.

• Colour coding simplifies workflow and reduces risk of mix-ups in busy labs.
