Hermetic waste liquor container for high-grade biosafety laboratory

The invention relates to the technical field of biological experimental equipment. In a high-grade biosafety laboratory, a great amount of waste liquor is produced in a biosafety cabinet, an isolator and other safety screens, generally contains pathogenic microorganisms with high risks, and cannot be put in a room in an exposure manner; in addition, the waste liquor can be brought out after being subjected to high-temperature and high-pressure sterilization by virtue of a high pressure sterilizer, and then is processed. The invention aims to provide a hermetic waste liquor container suitable for the high-grade biosafety laboratory. The hermetic waste liquor container comprises a tank (1), wherein a handle (2) is arrange at the upper part of the tank body, a seal cover (3) is arranged above the tank body, a quick joint end (4) is arranged at the joint between the sealing cover and the tank body, and a ball valve (5) is arranged on the seal cover and is connected with a high-temperature-resistant waterproof efficient respirator (7) through a connection end (6). The hermetic waste liquor container can be used for safely and efficiently disposing the various waste liquor produced in the high-grade biosafety laboratory and realizes double protection on experiments and personnel.
