Plain tube with clot activiator

Plain Clot Activator Blood Collection Tubes are intended for laboratory use in drug monitoring, serum biochemistry, and serum immunology testing. These tubes are manufactured from transparent PET or glass, with caps made from polyethylene or optionally rubber based on customer requirements. Each vacuum tube features a red 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 meet different laboratory needs.
