Solve the problem of reagent safe storage, intelligent experiment process, no contact. Waste liquid harmless treatment and other issues.Due to the complex storage environment of experimental materials and the nonstandard placement of reagents, the experimental environment needs to be safe and clean. Most of the final experimental waste liquid is directly discharged without harmless treatment, resulting in environmental pollution. Therefore, we design an experimental system that can collect, store, experiment and harmless treatment of waste liquid.The system is divided into three modules: storage, experiment and recovery.Through these modules, the experimental samples can be managed in a closed way to isolate leakage and pollution,. In the process of the experiment, the robot arm is used to realize the contactless intelligent operation. After the experiment, the waste liquid is sterilized by ultraviolet, treated by high temperature and high pressure, and then filtered layer by layer to reach the safe discharge standard.
