Introduction to Blood Collection Tube Manufacturing
Blood collection tube manufacturing is a critical process in the medical and diagnostic industry. Blood collection tubes, commonly called vacutainers, are sterilized glass or plastic tubes designed to collect, store, and preserve blood samples. They often contain additives that maintain the integrity of specific blood components for accurate testing.
The colored rubber stoppers on the tubes indicate the type of additive used, ensuring proper sample handling. Using the wrong tube can compromise test results, highlighting the importance of precise manufacturing and strict quality control. Modern blood collection tubes may include gel barriers, clot activators, or anticoagulants, which are essential for laboratory procedures such as serum separation, hematology analysis, and biochemistry testing.

Blood Collection Tube Manufacturing Process
The manufacturing process involves multiple stages, each critical to product quality and compliance.
1. Tube Molding
- Small plastic tubes are produced using molding machines, either electric or hydraulic.
- Uniform tubes are essential for accurate blood collection and laboratory testing.
2. Component Cleaning
- All components are cleaned to remove contaminants before assembly.
- Electroplating or surface finishing requires clean components for proper adhesion and quality.
3. Assembly Line
- Blood collection tubes are assembled on automatic or semi-automatic assembly lines.
- Standard throughput: up to 200 tubes per minute.
- Steps include tube feeding, stopper insertion, additive dosing, and labeling.
4. Sterilization
- Ensures all tubes are free from bacteria and viruses.
- Methods include gamma radiation, EtO, or steam sterilization depending on material type.
5. Quarantine (Finished Goods Store)
- Tubes are stored temporarily to ensure no defective or contaminated products reach the market.
Quality checks are performed before distribution.
