High Purity Serum Separating Gel for SST Vacuum Blood Collection Tubes Medical Additive

Our high-performance serum separation gel is professionally developed for vacuum blood collection tubes. Featuring a precise specific gravity formula and excellent thixotropic properties, it quickly forms a dense isolation layer after centrifugation to completely separate serum/plasma from blood cells. With stable physical and chemical properties and inert, contamination-free characteristics, it effectively avoids sample cross-interference and maintains long-term sample activity. It is widely applicable to clinical testing, biochemical experiments and in vitro diagnosis. Efficient separation and stable quality lay a solid foundation for accurate medical detection.

As a core special additive for vacuum blood collection tubes, serum separation gel is an inert polymer gel material and a key consumable for blood sample pretreatment and accurate detection. Adopting a refined proportioning process with strictly controlled density and viscosity parameters, the product delivers excellent thixotropy and phase separation performance.

Under standard centrifugation conditions, the gel achieves rapid layering and stable molding, forming a long-lasting and dense isolation barrier between serum/plasma and blood cells. It thoroughly prevents cellular substance diffusion and hemolysis, ensuring sample purity and detection accuracy from the source. Featuring high and low temperature resistance, radiation resistance and excellent stability, the product undergoes no chemical reaction with blood samples. Impurity-free and interference-free, it fully adapts to various medical detection items including biochemistry, immunity, hormones and tumor markers.

In addition, it boasts strong compatibility and can be compounded with various blood tube additives such as clot activators, EDTA and heparin, suitable for mass production of vacuum blood collection tubes of multiple specifications. With reliable quality, efficient separation effect and wide adaptability, it is widely used in hospitals at all levels, third-party medical laboratories and biological research institutions, providing standardized, efficient and dependable sample separation solutions for in vitro diagnosis and clinical testing.
