Unrivalled technologies to support your laboratory – Titanium Condenser and Technopolymer Splash Head
The UDK 149 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 149 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 149 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
Streamlined processes and enhanced service support with VELP Ermes Cloud Platform
UDK 139 features the unique connection option via Wi-Fi or LAN to VELP Ermes Cloud Platform, the Smart Lab solution allowing you to reduce routine operations thanks to the real-time monitoring of your Kjeldahl analysis wherever you are, at any time.
