The Getinge Bowie-Dick test is designed for daily monitoring of prevacuum steam sterilisers that operate with sub-atmospheric or trans-atmospheric cycles as defined in EN ISO 11140-4. The Getinge Bowie-Dick test comes with a graphic indicator which changes colours from blue to black to ensure the steriliser is functioning properly. If the Getinge Test detects excess air or condensable gases the indictor will leave a blue spot in the center of the sheet making it suitable to for any prevacuum sterilisers.
