Features
AutoDist Function
Thanks to the AutoDist function, measurements are unaffected by temperature differences within the device. This function recognizes the start of the condensation process and adjusts the distillation start time automatically in the individual measurement. This is achieved with a built-in temperature sensor within the condensate vessel and leads to more reproducible results.
Cooling Water Control
The cooling water control automatically saves water by intelligent flow limitation. Once steam distillation starts, water begins to flow through the condenser and the distillate is collected. Before and after distillation, the device automatically closes the cooling water valve. This feature saves approximately 20 % of water during determinations and eliminates concerns regarding the water supply.
Upgradeable on Demand
With our versatile components, you can easily upgrade and automate your system for highest convenience. All parts can be chosen separately and can be combined one after another. The modular design allows you to achieve an optimal combination of features to suit your individual needs. In this way, you receive the optimum combination of features and peripherals according to your needs.
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.
MaxAccuracy Mode
In laboratories, deviations of the supply voltage are possible within a range of up to 10 % of the original value. This can potentially affect the steam power output. In order to avoid these deviations, a voltage stabilizer is integrated to maintain the required supply voltage. This enhances measurement accuracy and ensures highest reproducibility for every result.
Aspiration
For more convenience and easier sample handling, we offer configurations with sample tube and receiver waste aspiration. This saves time and allows for smooth operation of the instrument.
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.
OnLevel Sensor
The OnLevel sensor is available for all configurations where no titration vessel is mounted. The sensor stops the distillation automatically after a defined condensate volume is reached. The sensor can be easily set and adjusted manually via a magnetic backplate. Obtain reproducible condensate volumes independent of the system lifetime.
Reaction Detection Sensor
The reaction detection sensor is available for MultiKjel configurations. 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.
Large Touch Screen
The intuitive touch screen provides fast feedback and enables easy process handling.
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.
