Description

Maximum Flexibility

The automatic Kjeldahl distillation unit UDK 149 can be connected to several models of external potentiometric titrators for direct output of the final result and offering choice and versatility to the user.

It enables the final result to be obtained directly with a considerable saving of time. All the parameters of distillation and titration phases are stored in the method with the advantage of time saving.

The high-precision pumps ensure constant accurate dosing of reagents. All the parameters concerning distillation and titration phases are easily programmable and stored in the archive on board the instrument, to be then downloaded via pen-drive or directly to PC for maximum management flexibility.

 

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 at 15 °C – 1 l/min at 30 °C) with minimal maintenance.

The titanium condenser ensures that distillate temperature always remains below the safe threshold value (35 °C), as indicated in the Kjeldahl method, without nitrogen loss.

 

Patented Steam Generator

The steam generator used by UDK Kjeldahl distillation units offers unique performance, being a patented solution

A thermostat ensures the correct functioning of the steam generator, a safety thermostat eliminates risks for the operator and guarantee safe working conditions.

The high level of precision and accuracy ensures correct and detailed results without any leaks even after intensive use.

  • Rapid (p)re-heating time
  • Low thermal dispersion
  • Great repeatability
  • High performance and resistance
  • Maintenance-free
  • Safety-thermostat
  • Works with deionized water
  • Total safety: no internal pressure

It is also possible to set the steam output from 10% to 100%.

 

Multitasking Software

Improved communication leads to improved efficiency.

The UDK 149 is a Kjeldahl automatic distiller equipped with a control panel with 3,5” high resolution colour touch-screen graphic display and easy to use multitasking software that guides the operator step by step through menus and sub-menus. Easy to read and practical with all the most important parameters available at a single glance, the multitasking software enables the operator to set all the parameters for a fully automatic distillation and titration processes.

  • Excellent usability
  • Multitasking software on a bright screen
  • Flexible, versatile and multi-language
  • Intuitive data entry and programming, very easy to upgrade
  • Unlimited library with all the analyses performed
  • Data export in .xls, .txt, .csv (according to LIMS) also on USB key
  • Direct access to the archive from remote PC in real-time without any download
