Kjeldahl digestion and distillation units are integrated laboratory systems designed for precise nitrogen and protein determination in food, feed, soil, and environmental samples. These assemblies typically feature 3 or 6 heating mantle positions with individual energy regulators, a fume duct for safety, and borosilicate glass components. They streamline the two-step Kjeldahl method, offering efficient digestion (up to

or more) and subsequent steam distillation for Kjeldahl nitrogen analysis

Key Features and Components 

• Combined System: Often provided as a single unit with a steel tubular stand, combining digestion and distillation sections, available in 3 or 6-test setups.
• Heating System: Utilizes individual electric heating mantles for each flask, allowing for independent temperature control (often with energy regulators).
• Capacity: Typically accommodates 250ml, 500ml, or 800ml Kjeldahl flasks.
• Safety Features: Includes fume ducts, water-cooled condenser racks, and sturdy, powder-coated Mild Steel (MS) frames.
• Automation Levels: Ranging from manual classical setups to semi-automated systems with pre-programmed distillation cycles, alkali addition, and, in some cases, automatic titration.
