Kjeldahl

behrotest^® standard digestion vessels have standard dimensions. That means they fit into digestion and distillation units of most brands. Of course, it also means that standard digestion vessels of most brands can be used with behr distillation units.

behrotest^® boiling stones are made from a ceramic material. Compared to conventional boiling stones made of glass, they provide optimum protection against defervescence due to their porosity and their shape, even with badly blended samples.
behrotest^® boiling stones are chemically pure and guarantee unadulterated results when determining the COD, the Kjeldahl nitrogen etc.

• Infinitely variable throughput
• Transparent protective shield for safe operation of the unit
• Exterior manual control elements with easy access prevent the analyst from touching hot glass parts
• Acid resistant diaphragm pump

The temperature-controlled InKjel TC-series devices combine the advantages of infrared and block digestion in one system: Fast Infrared digestion at defined temperatures ensures high sample throughput.
