Blood collection tubes are vital tools in the healthcare industry, facilitating the safe and efficient collection, storage, and transportation of blood specimens for diagnostic testing and medical research. At the heart of these tubes lies a small yet crucial component: the rubber stopper.

Rubber Stoppers for Blood Collection Tube serve as closures or seals at the open ends of blood collection tubes. They are typically made from synthetic rubber compounds that exhibit elasticity, durability, and chemical resistance to ensure the integrity of blood samples during handling and analysis. The primary functions of rubber stoppers include:

The foremost role of rubber stoppers is to create a hermetic seal at the tube's opening, preventing leakage or contamination of blood specimens. This seal is crucial for maintaining the integrity of blood samples, preserving their composition and preventing exposure to external elements that could alter test results. The material composition of rubber stoppers ensures a tight fit that withstands the rigors of transportation and processing in clinical laboratories.

Blood collection tubes often contain additives or anticoagulants required for specific diagnostic tests. Rubber stoppers are designed to be compatible with these substances, ensuring that they do not interact chemically or degrade over time. This compatibility is essential for accurate test results and ensures that the integrity of the blood sample is maintained until analysis.
