Graphite Digester

The graphite digestion apparatus generates uniform high temperatures by electrically heating graphite blocks, allowing samples and acids to undergo chemical reactions in a sealed environment to decompose organic matter or dissolve inorganic substances. It is used for laboratory sample pretreatment, converting solid samples into liquid form for subsequent testing, and is suitable for the analysis of heavy metals and trace elements in fields such as environmental science, food, and chemical engineering.
Selection
When selecting, consider matching the number of heating holes to the sample volume. Temperature control accuracy must meet method requirements, and corrosion resistance should accommodate common acid and alkali reagents. Heating speed affects processing efficiency, while safety features should include over-temperature protection and abnormal alarms. Maintenance should focus on the lifespan of graphite blocks and ease of cleaning.
