VAPODEST® is currently the most modern and powerful nitrogen analysis system on the market using the Kjeldahl method. This automated system is also ideal for the steam distillation of volatile acids, sulphur dioxide, TVB-N, ammonium, formaldehyde, phenol, alcohol, vicinal diketones or hydrogen cyanide.

  • Overview

    C. Gerhardt’s 130 years of experience in Kjeldahl analysis is evident in their line of VAPODEST® Kjeldahl Steam Distillation systems. The VAPODEST series offers powerful analytics, accurate results, and efficient, clean operation in one easy-to-use system. Precise pumps control the addition of reagents with maximum exactness. The steam pressure can be fully adjusted from 10 to 100 %. The unique, programmable "soft-start" function ensures controlled reactions. 

    The VAPODEST® models are available with different degrees of automation, from the simple smart version for a small number of samples to fully automated systems with integrated titration and an autosampler for high sample throughput. All versions are compatible with a variety of Kjeldahl digestion tubes and flasks. Any of these systems are ideal for total Kjeldahl nitrogen, free ammonia, phenol, or alcohol determinations. 

    All Gerhardt systems are designed with comprehensive safety features.
