Digestion system

HGD series graphite digestion robot is mainly used for the wet digestion of samples. It adopts the surrounding three-dimensional heating method. In the same digestion tube, it realizes "one-stop" automatic digestion through automatic acid adding, shaking, temperature control, acid driving, volume fixing and recording. It is an ideal pretreatment equipment for analytical instruments such as AFS, AAS, ICP-MS, etc. The digestion method of this system conforms to EPA, national standards and industry standards. Functions of the whole machine The instrument is composed of reagent selection system, reagent addition system, graphite heating system, lifting and shaking system, SCARA robot transmission system, over-temperature protection system, instrument control and data transmission systems. It can fully automatic complete the operation of reagent addition, sample mixing, temperature control, sample cooling and volume fixing. The instrument is designed for corrosion resistance. The overall frame is made of aluminum alloy, the key special parts are made of titanium alloy, the heating system is made of corrosion-resistant graphite with high thermal conductivity, the sample tube is made of PTFE, and the inside and outside of the whole machine are sprayed with multi-layer Teflon. All transmission parts are not exposed, which can withstand all kinds of strong acid and alkali corrosion for a long time. The transmission system adopts the industrial-grade heavy-duty anticorrosive robot SCARA, which has high positioning accuracy, and the transmission parts are not exposed, and the service life is long.
