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.

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.

How long should I archive the documentation of regular tests?

Keep the results according to your country/regional specific laws and guidelines. Those records can be of assistance in case of service as well.

Does my sterilizer need any periodic qualification/validation?

Validation generally comprises a range of tests defined in internationally recognised standards. These tests begin for every device with the factory tests at W&H. 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. For further information, please contact your dealer.

Whom should I contact to validate and maintain my sterilizer?

Validation shall be carried out by an official authority. Maintenance tasks shall be carried out by a qualified and authorized technician.

Should I pouch wrap my instruments and how long can I store them after sterilization?

To ensure that your instruments are stored in a sterile state from their successful sterilization until they are used, W&H recommends wrapping them in suitable sterile barrier systems before sterilization. The recommended storage period can be found in the recommendations of the wrapping material manufacturer. For further information, please contact your dealer.

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).
