  • 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.
  • 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.
