The Getinge Check Bowie-Dick Test Pack 134°C is for daily monitoring of steam sterilizers operating at 134°C. The test pack is packaged in an easy to open box and designed to operate in sterilizers with cycles as defined in EN ISO 11140-4.
If no appreciable air is present in the sterilizer chamber after vacuums are drawn, the steam will penetrate to the middle of the test pack and turn the indicator sheet a uniform black color, which indicates a pass. If a small amount of air is present, sufficient enough to cause a two degree temperature drop, the air will migrate to the middle of the test pack causing the center of the sheet to remain a blue/grey color rather than a uniform black. This indicates a fail.
