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. Accessing the 10 customizable methods available in 6 different languages is simple and intuitive. The new UDK 139 incorporates a considerably high level of technology, with the VELP patented steam generator that offers high performance, safety (no pressure inside) and is maintenance-free. Another unique VELP component is the patented titanium condenser offering reduced water consumption, ensuring that distillate temperature always remains below the threshold value above which some nitrogen can be lost. The unit works with a technopolymer splash head ensures durability to protect your investment requires no maintenance. A technopolymer housing ensures high resistance to chemicals used during the operation.
