Nitrogen determination according to Kjeldahl

behr "K" blocks with high-quality non-corrosive block casing made of stainless steel are optimally suited for nitrogen determination if the user is working with standards that allow for traditional block digestion systems, yet not infrared rapid digestion units.

Caution: For other acid digestions, such as for phosphate determination, it is absolutely necessary that the gases are first neutralized in a behrotest® extraction system (behrosog 3 or SIMVAC) before they enter the hood. The behrotest® micro digestion blocks make only use of 100 ml vessels, the macro series 400 ml vessels. 250 ml vessels are used for behrotest® standard digestion blocks.

All models (Inkjel), whether for power or temperature adjustment, have a uniform heating block size. Inkjel is the product for performing various types for digestion for your applications. With an Inkjel rack and the respective fume setup, various volumes can be digested.

The two-level behrosog process extraction system is a compact system for extracting and neutralizing aggressive acid vapors, especially from the Kjeldahl digestion for nitrogen determination. A pre-separator increases the safety level. Acid vapors are kept fully away from the environment.

For behr digestion units (K-block & Inkjel devices), extraction systems for acid vapors are a necessity. We differentiate between a simple water jet pump / SIMVAC and the behrosog 3 extraction system & neutralizer.

The behrosog 3 does not require a water connection but a power connection instead and can be used for all digestion blocks, the SIMVAC here can be used for max. 8 samples.

behr distillation units of the S series are the ideal supplement to the behr InKjel digestion systems. Depending on requirements, the user can choose between five steam distillation units. These are identical in the basic construction but differ in terms of operating comfort and degree of automation. The top model behr S 5 enables use with an external titration device.

On the basis of block and infrared digestion systems, the behrotest® complete systems offer the user various complete configurations for nitrogen determination according to Kjedahl.
