ICP/ICP-MS graphite digestion apparatus was used for sample pretreatme Model: XJ our advantages: 1. Fully enclosed design to prevent heat loss and acid fog intrusion; 2. Three-dimensional wrapping of high-quality graphite is heated, and the sample is heated evenly; 3. High efficiency, sample batch processing; 4.PID digital temperature control system, excellent performance; 5. Split type: Controller can be placed outside the fume hood, reduce acid gas corrosion, longer service life. Hole number :16, 20, 24, 36, 40, 42, 48 bit, can be customized temperature control range: room temperature -220 Temperature control accuracy Temperature difference between holes 1.5 Rated voltage :220V Heating power :2-3KW Continuous working time :48h
