Bowie-Dick Test Pack: Good practices

Chemdye® Bowie-Dick Test Pack detects air leaks, inadequate air removal and steam penetration level in vacuum-assisted steam sterilizers. The Chemdye® Bowie-Dick Test Pack consists of a chemical indicator sheet between porous material sheets and wrapped forming a package, with a steam indicator label. The central sheet, with a regular pattern, corresponds to a Bowie-Dick classic indicator.

Terragene® manufacture different presentations of Bowie-Dick Test Packs according to the market demands and regulations.

The Bowie-Dick Test Pack should be used daily, before running the first load of the day, after a sterilizer is installed or relocated, after a sterilizer malfunction, after sterilization process failures and after any major repairs of the sterilizer. A shortened cycle (i.e., a cycle omitting the post vacuum drying phase) should be run first to properly heat up the sterilizer.

Follow the instruction below for a valid result of the Bowie-Dick test:
Place the Bowie-Dick Test Pack horizontally with its label facing up in an empty vacuum assisted sterilizer chamber, in the bottom/front of the sterilizer rack, and over the drain.

Run the corresponding Bowie-Dick cycle.

After completing the cycle, retrieve and examine the chemical indicator sheet.

This indicator changes from yellow to dark brown/black when processed. Any  unexpected color change, such as lighter areas in the center of the sheet or different colors in the edges (i.e., a non uniform color change) indicates an air pocket during the cycle due to sterilizer malfunction.
