Reflux Digester

The reflux digester uses a heating and condensation reflux device to allow the sample and acid solution to undergo cyclic reactions in a closed system, decomposing organic matter and dissolving inorganic substances. It is used for sample pre-treatment, converting solid or complex samples into analyzable liquids, and is commonly employed in environmental, food, chemical, and other fields for detecting heavy metals or pollutant content.
Selection
When selecting a reflux digester, consider the sample type and testing standards, matching the heating power and temperature control range. Pay attention to the corrosion resistance of materials, such as polytetrafluoroethylene (PTFE) inner vessels. Ensure condensation efficiency and safety protection features. Determine specifications based on laboratory space and budget, prioritizing models that are easy to operate and have low maintenance costs.
