Our Vacuum Blood Collection Tube (Serum Clot Activator – Red Cap) is a high-quality sterile evacuated tube specially designed for safe, hygienic, and accurate collection of venous blood samples in hospitals, diagnostic laboratories, pathology centers, and clinical testing facilities. The tube is manufactured from medical-grade PET or polypropylene materials that provide excellent transparency, dimensional stability, and resistance to cracking during sample collection, transportation, centrifugation, and storage.

The inner wall of the tube is coated with a clot activator (silica particles) that accelerates blood coagulation and promotes rapid serum separation. This helps laboratories obtain clear serum samples within a shorter processing time, improving workflow efficiency and ensuring reliable analytical results for routine biochemistry, clinical chemistry, serology, immunology, hormone analysis, and other diagnostic investigations.

The pre-calibrated vacuum system is designed to draw the correct sample volume automatically, reducing collection errors and improving consistency between samples. A secure rubber stopper and precision-molded outer cap provide an effective leak-resistant seal that helps maintain sample integrity and minimizes the risk of contamination during handling and transport.
