2.0 mL Sodium Heparin Polypropylene Blood Collection Tubes (9×44 mm) – NH300PP

Fast Plasma Sampling Tubes with Heparin Anticoagulant

The NH300PP tube is a 2.0 mL blood collection tube in polypropylene, treated with sodium heparin anticoagulant, and sized at 9×44 mm externally. It features a screw cap (typically green for identification) and is designed for rapid plasma preparation, chemistry assays, and applications where immediate anticoagulation is required.

Key Features

• Volume: 2.0 mL — sufficient for many plasma-based assays.

• Anticoagulant: Sodium heparin — helps prevent clotting by accelerating antithrombin, enabling quick separation of plasma.

• Material: Polypropylene — durable, chemically resistant, better suited for handling, freezing, or varying lab conditions.

• Dimensions: 9×44 mm external — fits standard tube racks, centrifuge rotor holders, and many analyzers.

• Cap Colour & Type: Green screw cap (commonly used for heparin tubes) to provide rapid visual identification.

• Temperature Tolerance: Typically safe from −40 °C up to moderately high temperatures depending on lab protocols.

• Centrifuge Rating (RCF): Compatible with standard centrifuge speeds used for plasma separation.

• Packaging: Bulk options (e.g. 100 / 500 / 1,000 units) for efficient laboratory supply.

Why Choose NH300PP Tubes

• Ideal when quick plasma preparation is needed, with minimum delay or handling variation.

• Sodium heparin is suited for many chemistry and diagnostic assays where EDTA or citrate might interfere.

• Polypropylene build gives robustness against temperature fluctuations and rough handling.

• Green cap coding aligns with standard lab colour conventions for heparin tubes.
