VELP colorimetric titrator benefits:

• Completely automatic procedure
• Calibration-free
• Maintenance-free

The UDK 159 allows to constantly monitor the titration with the?real-time?graph displayed on the instruments.

Unrivalled technologies to support your laboratory – Titanium Condenser and Technopolymer Splash Head

The UDK 159 features the unique?VELP?patented titanium condenser?designed for efficient thermal exchange and low water consumption.

The distillate temperature is always kept below the Kjeldahl threshold value (35 ?C), as indicated in?the Kjeldahl method, without nitrogen loss.

• Reduced water consumption
• High resistance material with prolonged lifespan
• Reduced break risks during routine cleaning

The exclusive?VELP?Technopolymer Splash Head?incorporated in the UDK 159 is designed for high throughput providing state-of-the-art durability and resistance.

• Chemical resistant materials
• Unmatched lifespan of up to 10,000 analyses
• Maintenance-free and no risk of breaking

Reliability and safety for your lab

The UDK 159 is provided with the most complete set of safety features to ensure maximum operator safety. Sensors monitor tube in place, safety doors, reagent levels, cooling water flow-rate and more.

The?VELP Patented Steam Generator?guarantees?safe working conditions working without pressure:

• Rapid pre-heating time
• High performance and resistance
• Maintenance-free
• Works with deionized water

Nitrogen determination at high throughput gets to a new level with?VELP Ermes Cloud Platform.

Intuitive user interface ensuring ease-of-use

Bright 7″ color touch screen and?easy-to-use software?guide the operator step-by-step and provide fast feedback when setting the parameters and the analysis status.

Grant access to instruments and data only to specific people in your organization thanks to?the user management feature.

• 3 levels of authorizations and permissions according to GLP
• Clear readability of analysis time
• Intuitive menu and sub-menu navigation
• Dedicated service menu

TEMS? Technology

UDK Series Kjeldahl distillation units?work with the innovative?TEMS? benefits, for unmatched savings.

Time Saving: rapid heating reduces wasted time
Energy Saving: limited energy consumption thus cutting CO_²?emissions
Money Saving: cost reduction for each analysis
Space Saving: the narrow footprint saves valuable laboratory bench space

Vreceiver? boric acid with indicator sealed bags

VELP unique Vreceiver? is a certified formula composed of?Boric Acid powder?and a mixture of?indicators?mentioned by AOAC methods (Bromocresol Green?and?Methyl red) allowing?fast?and?standardized?receiving solution preparation for colorimetric titration.

The receiving solution is prepared in a few minutes facilitating the day by day operations instead of the typical time consuming process using single reagents. The result is a reliable and standardized solution for colorimetric titration.

Barcode technology for smart operations

The optional?barcode reader?matched with the?sample tubes with barcode?(Code A00000144) simplifies distillation data management and result?calculation.

The barcode on the tubes can be scanned in order to?transfer the data automatically for an optimized analysis workflow.

• Reduced risk of errors
• Automated processes
• Maximized efficiency
