China Bowie Dick Test Pack

China Bowie Dick Test Pack
Bowie & Dick Test Pack consists of two chemical indicatorsheets (125 x 113 mm) positioned between porous materials and areticulated foam sheet wrapped all together forming a package, with asteam indicator label.
The central sheet with a regular pattern corresponds to a Bowie & Dick classic indicator, i.e. BD Test Sheet.
The chemical indicator changes from yellow to dark brown/black when processed. Any unexpected color change,

such as the center of the test sheet being paler or a different color from theedges (i.e., there is a non-uniform color change) indicates that there was anair pocket present during the cycle due to sterilizer malfunction.The package has also a Warning Sheet that contains a circular chemical
indicator.
The Warning Sheet is placed at a lower point than the BD Test Sheet inside the package and allows rapid detection of failures in the
sterilization cycle.

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.
