Experience highest convenience & safety

• Innovative sensor technology that minimizes exposure of the user to chemicals.
• Intuitive touch screen for easy process handling.
• Upgradeable on demand to automate your analysis in the most convenient way.

Maximize accuracy & performance

• Automatic recognition of distillation start for perfect reproducibility.
• Distillation endpoint is recognized automatically for highest accuracy.
• Automated titration with connected titrators for minimum user interaction.

Save resources & time

• Optimized alkalization step for saving up to 30 % of reagent.
• Intelligent cooling water control for lower water consumption.
• No preheating required resulting in higher time-efficiency.
• Automated distillation & titration enables unattended operation.

Aspiration: For more convenience and easier sample handling, Büchi offer configurations with sample tube and receiver waste aspiration. This saves time and allows for smooth operation of the instrument.

AutoDist function: This function recognizes the start of the condensation process and adjusts the distillation start time automatically in the individual measurement.

Automatic titration: Automated titration is key to achieving the highest performance possible in Kjeldahl protein determination. Titration dosage, as well as endpoint recognition via suitable electrodes, is carried out automatically. This allows for minimum user interaction and high throughput at the same time.

Cooling water control: The cooling water control automatically saves water by intelligent flow limitation. This feature saves approximately 20 % of water during determinations.

OnLevel sensor: The sensor stops the distillation automatically after a defined condensate volume is reached. Obtain reproducible condensate volumes independent of the system lifetime.

Reaction detection sensor: It can save up to 30 % of NaOH reagent solution for the alkalization process so that you can work more cost-efficiently and environmentally friendly.

MaxAccuracy mode: In order to avoid supply voltage deviations, a voltage stabilizer is integrated to maintain the required supply voltage. This enhances measurement accuracy and ensures highest reproducibility for every result.

Splash protectors: Glass and plastic splash protectors are available. Glass splash protectors enable you to monitor the process to support method development and optimization. Plastic splash protectors are more robust and durable. Depending on the application, different splash protector variants enable the best performance.

Large touch screen: The intuitive touch screen provides fast feedback and enables easy process handling.

Safe operation: The Kjel Line instruments reduce user exposure to a minimum thanks to innovative sensor technology. Safety sensors monitor cooling water flow, steam generator pressure and if the sample tube is put correctly in place. Tank level sensors detect water, waste and reagent levels. The safety shields are fully transparent and equipped with secure control sensors. If the safety shields are opened during operation, the process is stopped automatically. The steam power is adjustable (10 - 100 %) and steam ramps are programmable to handle foaming samples.

Upgradeable on demand: With our versatile components, you can easily upgrade and automate your system for highest convenience. The modular design allows you to achieve an optimal combination of features to suit your individual needs.
