Key Features
- Improving safety
A high accuracy bellows pump gives long term stability in delivery of the alkali. The unit is equipped with a wide range of safety features including safety door, plus level pins and overpressure sensors for the steam generator. The door completely covers the area in front of the operator and the unit cannot be operated with the door open. The drip tray can easily be removed for cleaning.
- Approved method
Official and accurate procedures (ISO, AOAC, EPA, DIN) simplify validation.

Key Features
- Safety features
A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use.

Key Features
- Unmatched Accuracy
The superior performance of a KjeltecTM titration system is based on colorimetric measurement of a precise chemical reaction for end-point detection. Accuracy is assured time after time with the additional benefits of long-term stability, wide working range, speed and simplicity without the need for repeated and costly calibration procedures.
- Safety features
A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use.
- Autosamplers
An optional 20 or 60 place Autosampler provides the benefits of automation even at lower sample throughputs. Just load your sample racks directly from the digestion block and KjeltecTM will perform accurate analysis unattended for more than four hours.
Key Features
SAfE Technology
The patented SAfE* technology improves safety by a mixing procedure, reducing the exothermic reaction between alkali and acid during distillation and removing the need for manual pre-dilution.
