Temperature-controlled digestion apparatus

The temperature-controlled digester uses electric heating and temperature sensors to control the heating of samples in acid solution, decomposing organic matter into inorganic ions. It is used for detecting heavy metal content in water samples in environmental monitoring, determining total nitrogen in proteins in food testing, and pretreating samples before industrial wastewater treatment.
Selection
When selecting, consider matching the sample capacity with the number of digestion tubes, ensuring the temperature range covers the commonly used 150–300℃, and note that the heating rate affects digestion efficiency. The corrosion-resistant material should withstand strong acid environments, and safety features must include over-temperature protection and pressure relief design. Temperature control accuracy is crucial for result reproducibility, while ease of maintenance helps reduce operational costs.
