In biology experiments, often use the biological safety cabinet and ultra-clean bench for related experiments. The waste and liquid generated during the experiment are usually placed in the waste tank, and the waste and liquid need to be separated after the experiment. The traditional waste liquid tank for ease of operation are generally open settings, discard waste and waste liquid process is prone to liquid splash, is not conducive to the conduct of aseptic tests, while toxic and hazardous liquids are easy to splash out of the safety of accidents.
Laboratory in the treatment of chemical, biological and medical waste, usually by incineration and burial. However, when in the laboratory, if there are infectious biological specimens, as well as disposable consumables used in the test process, before sent to the municipal medical waste unified recycling, need to do pre-treatment to reduce the sample infectious, such as cracking with acid. This utility model for the collection and cracking as one of the new waste cylinder, and can avoid the waste thrown into the cylinder when the acid splash and will be cracked when the waste is taken out of the leftover acid dripping outside the cylinder, for the convenience of the majority of experimenters.
