Outstanding Reliability Maintenance-free, resistant, patented steam generator Patented titanium condenser for unmatched performance Durable technopolymer splash head Chemically-resistant technopolymer housing
Operator Safety Lever operation simplifies tube insertion / removal (all sizes) Protection screen for distillation chamber Drip tray collects splashes Zero pressure steam generator
Ecology & Standards Performs to AOAC, EPA, DIN and ISO standards Incorporates TEMS™ technology* Automated water supply control reduces consumption
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.
UDK 159 Kjeldahl Analyzer - TEMS™ Technology
Time Saving - Fast and frequent analyses; no heating delay between runs Energy Saving - Cooling water consumption starting from only 0.5 l/min; excellent insulation Money Saving - Cost reduction is substantial, in line with reduced power consumption Space Saving - The extremely compact footprint saves useful laboratory bench space
UDK 159 Kjeldahl Analyzer - Fully Automated Analysis
The completely automatic Kjeldahl distillation and titration system offers great performance and the maximum in terms of safety for the user.
Automatic addition of all the reagents involved (sodium hydroxide, water, boric acid, titrant solution) with low level warning simplifies the routine activity whilst the possibility to set the steam output from 10% to 100% enlarges the application range of UDK 159. Automatically the unit will perform distillation and titration.
At the end of the analysis, all the residues can be aspirated automatically, both for distillation and titration.
UDK 159 Kjeldahl Analyzer - Exclusive Titanium Condenser
VELP Scientifica has developed and patented the innovative titanium condenser able to ensure high performance and considerable water savings (from 0.5 l/min). The graph shows the high efficiency of the titanium condenser compared to the traditional glass one available on the market. The titanium condenser ensures that distillate temperature always remains below the safe threshold value (35 °C), as indicated in the Kjeldahl method.
