behrotest® InKjel digestion units are equipped with a high-performance infrared heater.

• Direct heating of the samples by the infrared heater prevents the endlessly long heating times required using conventional heating block systems
• High quality quartz heaters instead of the common steel tube heater ensures particularly homogeneous heating in all sample positions

Quality and position of the behr infrared heater guarantee the user identical heating phases and digestion temperatures in all sample positions. This also applies to the double-row arrangement of 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 aluminium heating block.

This makes the behrotest® InKjel the ideal digestion system for nitrogen determination according to Kjeldahl and other high temperature digestions. In Kjeldahl digestions, the temperature is adjusted through the boiling point of sulphuric acid.
