Patent ID: 8337776

Claim:
A system to safely dispose of hazardous liquid waste, comprising: a glove box for conducting a test with a hazardous liquid material therein, the glove box having a drainage line connected to a waste tank for directing the hazardous liquid waste from the glove box to the waste tank; a waste disposal line connected at one end to the waste tank and at a second end to a waste container; and a double-valved connector connected at one end to the waste disposal line and at the opposite end to the waste container; the double-valved connector including a coupling insert secured at one end to the waste container and having a first biased valve closing the opposite open end thereof, the double-valved connector having a coupling body secured at one end to the waste disposal line and having a second biased valve closing the opposite opened end thereof, and the coupling insert being removably secured to the coupling body whereby when the coupling insert is secured to the coupling body the first and second biased valves are open so that liquid waste can flow from the waste tank to the waste container; and when the coupling body is uncoupled from the coupling insert, the first and second biased valves in the coupling insert and the coupling body are biased closed such that both the waste tank and the waste container are completely sealed to the surrounding environment.
