      FAQs

      • What is validation?
        Validation is a testing procedure carried out by an official authority, proving the effectiveness of your sterilizer. Compulsories and frequency of validation are regulated by local/national guidelines. more
      • Do I need to document the results of all periodic tests?
        W&H recommends recording all periodic tests, repairs and modifications on the sterilizer in a logbook including date and signature of the person who carried out the test or other activity. Compulsoriness of recording is regulated by local/national guidelines. more

In addition, corresponding documentation is included with your device. Prior to commissioning the device at your premises, the technician performs further checks to ensure the device functions correctly. Then, depending on the national/regional laws and directives, the device must be subjected to a so-called renewed performance qualification at regular intervals.

      • Which water quality should I use for my Lexa Plus sterilizer?
        The water quality for sterilizers is internationally specified by standards and directives. The reasons for this are that your sterilizer can be seriously damaged by it or the sterilization can be jeopardised. Consequently, only water with conductivity of less than 10 µS/cm in North America and 15 µS/cm for the rest of the world should be used for your W&H sterilizer. The Multidem system and OSMO are especially designed to prepare suitable water (see chapter “Water quality” in the Instructions for Use). more
