The preparation of the boric acid receiving solution for colorimetric titration has never been so easy thanks to the Velp Scientifica Vreceiver~(TM). During the Kjeldahl distillation process, the ammonia content is condensed and collected in a boric acid solution to avoid loss of gaseous NH3. For the calculation of the results, it is possible to perform a colorimetric titration where the determination of Total Kjeldahl Nitrogen involves the titration of ammonia present in the distillate through the detection of the colour change in the titration vessel.
