Automatic Distillation Unit with Titrator Connection

The UDK 149 operates automatically, after setting on the multi-function 3.5” color touch screen water, boric acid and sodium hydroxide addition, distillation time and the steam generation output level between 10 and 100%.

Different automatic titrator models can be connected to the UDK 149 for direct output of the final result and offering choice and versatility to the user. The high-precision pumps ensure constant accurate dosing of reagents. All the parameters concerning distillation and titration phases are easily programmable.

Simple, time-saving and intuitive operation is assured by direct access to the 20 customizable methods available in 6 different languages (additional languages are also available). The UDK 149 offers powerful archiving features. In compliance with GLP (Good Laboratory Practice), the interfaces enable results to be downloaded to a pen drive or directly to a PC. The .xls format permits operators to use well-known software for extracting reports with maximum flexibility.

The new UDK 149 incorporates the latest technology. The VELP patented steam generator is maintenance-free and offers high performance and an outstanding level of safety (no pressure inside). Also unique from VELP is the titanium condenser offering reduced water consumption, a high resistance to breakage and the guarantee that distillate temperature always remains below the safe threshold value to retain total nitrogen. A technopolymer splash head significantly increases the life expectancy and requires no maintenance. All chemical reagents used during the process are resisted by the technopolymer housing.

Full user protection is top of the benefits of the UDK 149. A range of sample tube sizes can be inserted without any effort using a lever to displace the tube support and clamping the tube in place securely because of the innovative design.

The versatility of the UDK 149 is underlined by input from a titrator and data output to PC, pen drive and printer, in a common format, via USB, Ethernet and RS232 plus an on-board archive for sample data storage. Offering an upgrade pathway to combine distillation and titration, the UDK 149 will be instrument of choice for many laboratories.
