Abstract
The utility model relates to a chemical luminescence immunoassay technique field especially relates to a quality control article container, including the pipe body, end cover and mounting seat, end cover is respectively screwed in the top of pipe body, the top of pipe body is established with first thread groove, the top of end cover is established with through slot, the middle of end cover is established with second thread groove, the inner top of second thread groove is connected with sealing sleeve, the top of mounting seat is fixed with storage jar, and the lateral wall of storage jar is equipped with solenoid valve, the utility model discloses compared with traditional quality control article container, through the cooperation of pipe body, end cover, through slot, first thread groove and second thread groove, can one -step tighten end cover and cancel secondary tightening procedure, avoid the freeze -drying mode of traditional technology to use half -rotation cover and cause part end cover to tighten too tightly liquid to be unable to sublimate, thereby improve freeze -drying quality, improve through slot plugging convenience through the cooperation of storage jar, solenoid valve, laser emitter and injection needle, thereby improve quality control article packaging efficiency.
