Caps are typically made from rubber (butyl) and plastic (polyethylene) to ensure a secure, airtight seal.
2. Tube Molding (Casting): Precision injection molding techniques are employed to create the tube body with exact dimensions and wall thickness. This ensures consistent vacuum pressure and structural integrity.
3. Additive Dispensing: A critical step involving the precise measurement and dispensing of coagulation sodium citrate solution (typically 3.2% or 3.8%) into each tube. This is done under sterile, controlled conditions to achieve the exact plasma-to-anticoagulant ratio (1:9 or 1:4) essential for accurate coagulation testing. Advanced volumetric dispensing systems are calibrated daily.
4. Vacuum Creation: Following additive dispensing, a controlled vacuum is created within the tube. This ensures the correct draw volume of blood during venipuncture, preventing under-filling or over-filling which can significantly affect test results. Vacuum levels are meticulously monitored and adjusted.
5. Capping and Sealing: The tube is immediately sealed with a rubber stopper and an outer plastic cap. This process ensures the vacuum is maintained and prevents leakage and contamination. Automated capping systems are used to minimize human intervention.
6. Labeling and Barcoding: Each tube receives a high-quality label with critical information, including lot number, expiration date, and CE/FDA markings. Barcoding facilitates automated sample tracking and data management in laboratories.
7. Sterilization: Our Pro-Coagulation Tubes undergo sterilization via gamma irradiation or ethylene oxide (EtO) to ensure aseptic conditions, meeting ISO 11137 (Radiation Sterilization) or ISO 11135 (EtO Sterilization) standards. This is crucial for patient safety.
8. Quality Control and Testing: Comprehensive testing is performed at various stages, including dimensional checks, vacuum retention tests, sterility tests, and functional performance tests (e.g., coagulation factor stability). Our products meet or exceed international standards like ISO 6710:2017 for single-use container111s for human venous blood specimen collection.
9. Packaging: Tubes are carefully packaged in robust, sterile-barrier packaging to protect them during transit and storage, maintaining their integrity until use.

This rigorous process ensures a service life of typically 18-24 months for our Pro-Coagulation Tubes. Target industries include clinical laboratories, hospitals, blood banks, research institutions, and pharmaceutical companies globally. The advantages manifest in typical application scenarios such as improved diagnostic accuracy, reduced pre-analytical errors, and enhanced laboratory workflow efficiency.
