Programmed Digestion Furnace JRX-15S, 15 Positions (CAT#: STEM-AL2-4119-ZJF)

The JRX-15S programmed digestion furnace is a laboratory heating system for parallel sample digestion. It is intended for preparing samples before nitrogen analysis and other wet-chemical procedures. Digestion tubes are placed into dedicated heating positions within the heating block. The block transfers heat directly to the tubes to support consistent sample treatment. Electronic temperature regulation controls the heating process during digestion. The multi-position layout allows several samples to be processed in the same operating cycle. The instrument includes control and protection functions for routine laboratory heating. Its configuration supports standardized sample preparation before downstream analytical measurement.
