Plain tube with gel

Gel & Clot Activator Blood Collection Tubes are designed for laboratory use in drug monitoring, serum biochemistry, and serum immunology testing. These tubes are made from transparent PET or glass, with caps manufactured from polyethylene or optionally rubber, depending on customer requirements. Each vacuum tube features a golden color-coded safety cap with a rubber piston for secure sealing, and the inner wall is coated with a clot activator that promotes the coagulation process when the tube is gently inverted. The tubes are available in both sterile (gamma-irradiated) and non-sterile versions and come in various sizes to accommodate different laboratory needs.
