Bio-Mark, is used in laboratories for collecting biohazardous waste for disposal. The product is made from a special composite material from UK's BP, and through a unique process, it possesses higher mechanical strength than ordinary sterilization bags, being tough, puncture-resistant, and capable of withstanding continuous high temperature and high pressure. The specially designed double-sealed bottom ensures excellent sealing, no leakage, and high mechanical strength, with the interface able to bear significant weight without breaking when the bag is lifted while full of waste. The bag body is printed with warning symbols and the word "BIOHAZARD".  When in use, directly place culture waste and other materials into the high-temperature, high-pressure sterilization bag. Please keep the bag open (do not seal or tie knots to avoid breakage, leakage, or failure to achieve sterilization) before placing it into the autoclave for sterilization and subsequent disposal. Additionally, the sterilization bag should not be used directly to hold sharp items.
