[0002] Purification equipment is a type of equipment used to improve air quality. They use different technical means to reduce or eliminate pollutants in the air. Laboratory workbenches are work platforms designed specifically for laboratory environments. When conducting experiments in the laboratory, workbenches are needed to place instruments and process materials. After the experiment, there will often be some waste materials and garbage left on the workbench, which need to be cleaned and purified for the next use.
