Description
Advanced Clot Activator Technology
Our vacuum blood collection tubes feature precision-coated interiors with optimized coagulant formulation. The clot activator promotes rapid yet controlled blood coagulation, preventing hemolysis while ensuring transparent serum separation after centrifugation. This pro-coagulation tube design is specifically engineered for serum-based biochemical and immunological analyses.
