In the realm of medical diagnostics, vacuum blood test tubes play a pivotal role in collecting and preserving blood samples for a wide range of clinical tests. These tubes are designed to create a vacuum within the tube, ensuring efficient blood collection and minimizing the risk of contamination. An integral component of vacuum blood test tubes is the cap, which serves as a critical barrier against spillage, leakage, and environmental contaminants.

Our Vacuum Blood Test Tube Caps – K2 are typically manufactured from two primary materials: polyethylene (PE) and thermoplastic elastomers (TPE).

– PE, a versatile and durable plastic, offers excellent chemical resistance and can withstand sterilization processes.

– TPE, on the other hand, provides superior flexibility and elasticity, enabling a tight and secure seal around the tube.


PE and TPE caps offer a range of valuable features that enhance the performance and safety of vacuum blood test tubes:

-Leakproof and Secure Seal: The combination of PE’s rigidity and TPE’s flexibility ensures a tight and secure seal around the tube, preventing spillage and leakage during transport and storage.

– Puncture Resistance: PE’s durability protects the tube from punctures and tears, safeguarding the integrity of the blood sample.

– Sterilization Compatibility: Both PE and TPE can withstand sterilization methods, ensuring the caps remain free from contaminants.

– Biocompatibility: PE and TPE are considered biocompatible materials, meaning they do not interact adversely with biological tissues, minimizing the risk of sample contamination.

PE and TPE caps are widely used in various types of vacuum blood test tubes, including:

– Serum Tubes: These tubes contain a clot activator that causes blood to clot, separating the serum from the cellular components. PE and TPE caps ensure the serum remains intact for analysis.

– Plasma Tubes: These tubes contain an anticoagulant that prevents blood from clotting, preserving the plasma for further testing. PE and TPE caps maintain the integrity of the anticoagulant and prevent coagulation of the plasma.

– Whole Blood Tubes: These tubes collect blood without any additives, preserving its original composition for various hematology tests. PE and TPE caps safeguard the whole blood sample from contamination.

In addition to the features listed above, our products are also: highly durable, aesthetically pleasing, and competitively priced.
