Three Levels of Cleanliness
Description Cleaning process Packaging External Packaging Comments “Uncleaned” Deionised water in a conventional washing machine with brushes “Grey” room conditions Plastic storage boxes None Recommended if a thorough cleaning procedure is used prior to further processing “Ultrasonically cleaned” Automated ultrasonic cleaning line using multiple wash steps of varying pH’s, rinse steps and final drying stage. Class 100 clean room Recommended if a simple cleaning procedure is used prior to further processing “Clean room cleaned” Sealed in air-tight laminated foil pouches under inert Argon atmosphere Glass may be used without any cleaning steps
