In the evolving landscape of blood collection and diagnostics, the lithium heparin tube stands as a critical innovation for accurate plasma analysis. This comprehensive guide explores the industry dynamics, technological parameters, usage scenarios, and manufacturer perspectives relevant to lithium heparin tube, with a special focus on the lithium heparin tube series and products developed by Shijiazhuang BDT Heating Pad Co.,Ltd.
A lithium heparin tube is a crucial blood collection device pre-filled with lithium heparin, an anticoagulant agent, ensuring that blood remains unclotted for precise plasma-based diagnostics. Its applications span clinical chemistry, biochemistry assays, hormone levels testing, and more. Empowered by advanced manufacturing, innovations such as the lithium heparin gel tube provide enhanced sample separation and improved workflow efficiency.
Shijiazhuang BDT Heating Pad Co.,Ltd.’s leading product, the Sodium Fluoride - Lithium Heparin Tube, encompasses:

The global demand for efficient plasma separation and advanced diagnostic accuracy is fueling profound innovation in lithium heparin tube manufacturing. The current market emphasizes:
Specification | Standard Value | Industry Range | |
---|---|---|---|
Min | Max | ||
Tube Material | PET/Glass | PET | Glass |
Vacuum Volume | 2-5ml | 1ml | 10ml |
Heparin Content | 12 IU/ml | 10 IU/ml | 30 IU/ml |
Cap Color | Green | Light Green | Dark Green |
Gel Barrier | Optional/Present | Absent | Double Layer |
Centrifugation Speed | 1300–2000g | 1000g | 3000g |
Temperature Stability | 4–25°C | 0°C | 37°C |
The main materials are medical-grade PET (polyethylene terephthalate) or borosilicate glass. PET is preferred for its shatter resistance, biological inertness, and lightweight handling.
Lithium heparin tube anticoagulant fill is calibrated (typically 12 IU/ml of blood) and complies with standards such as ISO 6710 and CLSI GP39.
The gel barrier facilitates clear phase separation between plasma and cellular elements after centrifugation, improving sample purity and automation compatibility (Clinical Chemistry and Laboratory Medicine).
Universally, lithium heparin blood collection tubes feature a green or light-green cap, per industry recommendations for safe identification.
Standard tube sizes include 13x75mm (2–3ml) and 13x100mm (4–6ml), though customization is available.
Typical protocols: 1500g, 10 minutes at 4–25°C, per AACC recommendations.
ISO- and CE-certification, batch traceability, and validation experiments ensure every tube meets analytical, clinical, and safety standards.
