Description

This pack of Serum Separating Gel Tubes (SST) contains 100 sterile Vacutainers designed for efficient blood collection and rapid serum separation in clinical chemistry and immunology. Each tube is recognizable by its industry-standard yellow color-coded safety cap and contains two primary additives: a specialized clot activator to speed up the natural coagulation process and a thixotropic polymer gel at the base. During centrifugation, the gel forms a physical barrier between the serum and the blood cells, preventing nutrient exchange and ensuring sample stability for transport or long-term storage. These tubes are essential for maintaining high specimen quality and reducing manual handling in high-volume laboratory settings.
