Automatic Graphite Digestion System is a new type of pretreatment equipment that leads the development direction of wet digestion after electric furnace, electric hot plate and ordinary electric heat digestion system. It can realize automatic and continuous processing of samples under the condition of no one is on duty. The instrument automatically completes the process of feeding acid (multiple times), capping and removing, programmed temperature rising, acid drive, volume setting, sample mixing, sample transfer, and the whole process is unmanned, and the "one-button" process is standardized, programmed, and automated, which is goodbye to the monotonous, repetitive, cumbersome, and hazardous experience of sample digestion, and redefine the process of wet digestion.
