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:

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

Features

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

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.
