Intelligent Graphite Digestion Instrument
The digester is a pre-processing equipment for sample element analysis and testing. When sample analysis and testing in environmental monitoring, agricultural inspection, commodity inspection, and quality inspection departments, the sample pre-processing time accounts for about 70% of the entire analysis and testing time. Therefore, the new generation of sample pre-processing equipment is The key to improving the efficiency of sample analysis and testing.
Characteristics
High-purity graphite heating element, good temperature uniformity, batch sample processing, greatly saving labor costs and acid consumption, and more economical;
