Infrared Kjeldahl Digestion

These digestion units are compact and well insulated to minimize heat transfer to the surroundings and allow fast, even heating thus giving good working conditions as well as saving energy.

The Kjeldahl method is the official method for determining nitrogen and protein contents in:

• Animal feeds
• Soils, Fertilizers, etc.
• Lubricants, fuel oils, etc.
• Waste water, sludge, etc.
• Foods (Raw materials and finished products)

Features

• Fitted with quartz infrared heaters
• Ceramic insulation for efficient heating
• 250 mL capacity digestion tubes (quartz).
• PID Controller with auto-tuning to maintain precise temperature.
• Includes rack with handle for easy loading and unloading of digestion tubes

Technical Specifications

• Digital PID Controller for precise control
• Input Voltage: 220 V AC ± 10%, 50/60 Hz

Quartz Digestion tubes: Quartz Digestion tubes are excellent for use in Kjeldahl analysis. Unlike borosilicate glass, Quartz can withstand sudden heating and cooling. Quartz tubes can withstand temperatures up to 1000°c and hence boiling Sulfuric acid at 420°c can be easily done without the fear of breakage. Quartz is better resistant to sulfuric acid attack at elevated temperatures than borosilicate glass.
