The ESR Blood Collection Tube with Composite Antimony Anticoagulant is a specialized clinical device designed for erythrocyte sedimentation rate (ESR) testing, with a high production capacity of 12,000 pieces per hour. Formulated with a composite antimony-based anticoagulant, it effectively prevents blood clotting while maintaining the natural properties of erythrocytes, ensuring accurate ESR measurement results. The tube’s design is optimized for compatibility with standard ESR testing instruments and centrifuges, streamlining laboratory workflows. With its high-volume production capability, it meets the demands of large-scale clinical facilities, diagnostic laboratories, and high-throughput testing environments, providing reliable specimen collection for routine and emergency ESR assessments.
ESR tubes incorporate advanced engineering to deliver superior clinical performance:
| Feature Category | Technical Specification | Clinical Value |
|---|---|---|
| Contamination Prevention | Closed vacuum system; direct blood transfer to anticoagulant tube | Eliminates operator exposure; reduces lab contamination; complies with biosafety standards |
| Operational Efficiency | Distinctive black cap; pre-measured anticoagulant; ready-to-use | Streamlines workflow; reduces sampling errors |
| Result Precision | 0.129mol/ L(anticoagulant:blood=1:4); concentration-controlled | Ensures consistent anticoagulation; prevents ESR deviations |
| System Compatibility | Compatible with major automated ESR analyzers (e.g., ESR-30/40); LIS/HIS integration | Enhances lab efficiency; reduces transcription errors |
| Interference Resistance | Specialized anticoagulant minimizes effects of icteric/hemolyzed/lipemic samples | Expands detectable sample range; improves reliability in pathological states |
