A Digestion Furnace (also known as a digester or block digester) is a laboratory equipment primarily used for digesting samples in preparation for further analysis, typically used in environmental, agricultural, and food testing laboratories. The furnace provides a controlled high-temperature environment, typically decomposing complex organic materials into simpler forms through acid digestion. This process is crucial for analyzing the elemental composition of a sample, especially for determining the concentration of elements such as nitrogen, phosphorus, or heavy metals.
