Automatic Kjeldahl Analyzer
The UDK 159 Kjeldahl Analyzer runs automatically, after setting sodium hydroxide, water and boric acid addition, the steam generation output from 10 to 100% using the innovative 6” color touch screen. The high-precision pumps and burette ensure constant accurate dosing of reagents and with the integrated colorimetric titrator (AOAC recommended) you will have reliable results concerning your nitrogen and protein determinations. Automatic titration vessel cleaning provides significant advantages including reducing maintenance to a minimum.
