This Non-Vacuum Blood ESR Tube is made from high-quality polystyrene (PS) or polypropylene (PP) material. The inner wall is treated with siliconization, creating a smooth surface that reduces blood adhesion and fibrin deposition, ensuring efficient and accurate serum separation. It contains 3.8% Sodium Citrate as an anticoagulant to prevent platelet aggregation effectively, ensuring sample accuracy and reliability. This tube is widely used for applications such as Erythrocyte Sedimentation Rate (ESR) testing and blood chemistry analysis.

Feature Of Non-Vacuum Blood Collection ESR Tube

● Unique Siliconized Inner Wall: Unlike traditional blood collection tubes, the siliconized inner wall minimizes blood residue and fibrin adherence, improving separation efficiency and ensuring accurate test results.

● High-Performance Anticoagulant Protection: Contains a precise proportion of 3.8% Sodium Citrate, uniformly distributed within the tube, effectively preventing platelet aggregation and making it ideal for ESR and blood chemistry analysis.

● Flexible Size Options: Available in multiple sizes and capacities, suitable for various testing needs and compatible with most automated blood analyzers on the market.

Applications Of ESR Tubes

● ESR (Erythrocyte Sedimentation Rate) Testing

The non-vacuum design, combined with the 3.8% Sodium Citrate anticoagulant, makes it ideal for ESR testing. After blood collection, gently invert the tube to mix with the anticoagulant, which prevents platelet aggregation, ensuring accurate and consistent ESR results.

● Blood Chemistry Analysis

In blood chemistry testing, the high-quality gel in this tube facilitates effective serum separation, ensuring sample purity and stability. Suitable for use with a centrifuge, this tube enables easy extraction of uncontaminated serum samples for precise biochemical analysis.

● Hematology

The black-top design and reliable anticoagulant properties make this tube ideal for hematology tests, such as complete blood count (CBC). Its anticoagulant feature prevents cell lysis, preserving the integrity of red and white blood cells for accurate readings.
