Kjeldahl Steam distillation System, Semi-automatic Version


Item Code: S1


Kjeldahl Steam distillation System, Semi-automatic version, NaOH is added and distillation started and ended at the touch of a button, Encl. set of canisters for H2O and NaOH. 

The Steam Distillation Units behr S1 are real ‘all-rounders’ in sample preparation. With these devices, proteins, nitrate, nitrite, ammonia, volatile acids, ethanol, formaldehyde etc. can be measured in different samples.


A typical field of application is the treatment of subsequent Kjeldahl digestion by distilling ammonia in an acid receiver. Furthermore, volatile preservatives in canned fish or meat salads are distilled to subsequently carry out a photometric

determination. Steam distillation is also used to separate alcohols in spirits (e. g. egg or cream liqueurs) for later quantitative analysis.


The unique versatility of the behr S1 units are underlined by their additional use in water and environmental chemistry for the determination of volatile organic acids (e. g. sewage sludge).
