Product Description
Semi-automatic Kjeldahl distillation unit for your analyses concerning different applications such as determining ammoniacal nitrogen, protein determination, nitrogen content (Kjeldahl or direct alkaline distillation), nitric nitrogen (after reduction/Devarda), phenols, volatile acids, cyanides and alcohol content. The semi-automatic Kjeldahl distillation unit UDK 139 runs automatically, after setting distillation time, sodium hydroxide and water addition and steam generation output level between 10 and 100% using the innovative 3.5'' color touch screen. The high-precision pumps ensure constant accurate dosing of reagents.
