Infrared rapid digestion devices for nitrogen determination according to Kjeldahl

The digestion units of the model series behrotest® InKjel are equipped with a high-performance infrared heater. Quality and position of the behr infrared heater guarantee the user identical heating phases and digestion temperatures at all sample positions.This also applies to the double-row arrangement for racks for 12 samples.

The glass digestion vessels are suspended in the rack and are not deposited at the bottom of the digestion unit. Therefore the digestion units are less susceptible to breakage than in an aluminum heating block.This makes the behrotest® InKjel the ideal digestion system for nitrogen determination according to Kjeldahl and other high-temperature digestions. In the Kjeldahl digestions, the temperature is adjusted through the boiling point of sulfuric acid.

Direct heating of the samples by the infrared heater prevents the endlessly long heating times required using conventional heating block systemsHigh-quality quartz heaters instead of the common steel-tube heater ensure particularly homogeneous heating at all sample positions.
