Routine Testing for Pre-Vacuum Steam Sterilizers
The Bowie-Dick Test Pack is used to evaluate the effectiveness of air removal and steam penetration in pre-vacuum steam sterilizers.
Effective air removal is essential because residual air within the sterilizer chamber can interfere with steam contact. The test provides an important routine check of the vacuum system before instruments and other loads are processed.
This box contains 50 Bowie Dick test packs, making it suitable for healthcare facilities performing regular steam sterilizer testing.
What Is a Bowie Dick Test?
The Bowie Dick test is a specific performance test used with pre-vacuum steam sterilizers.
Its purpose is to help identify problems associated with:
- Inadequate air removal
- Air remaining within the chamber
- Conditions affecting steam penetration
- Vacuum system performance
Traditional Bowie Dick testing used specially prepared packs made from folded 100% cotton surgical towels with a test sheet positioned in the centre.
Modern commercially available disposable Bowie Dick test packs provide a more convenient alternative to preparing the traditional towel pack.
What Does a Bowie Dick Test Pack Detect?
The Bowie Dick test pack is primarily used to evaluate whether the pre-vacuum sterilizer is effectively removing air before steam sterilization.
Residual air can prevent adequate steam contact with parts of the load.
The test therefore provides an important indication of the sterilizer’s air-removal performance before routine processing begins.

When Should a Bowie Dick Test Be Performed?
The supplied product information recommends performing the test each day that a vacuum-type steam sterilizer is used and before the first processed load.
Facilities should always follow the sterilizer manufacturer’s instructions and their applicable infection-control and sterilization protocols.
Where Is the Bowie Dick Test Pack Placed?
For the traditional test procedure described in the supplied information, the test pack is positioned:
- Horizontally
- In the front-bottom section of the sterilizer rack
- Near the sterilizer door
- Over the drain
- In an otherwise empty chamber
For commercially manufactured disposable test packs, users should follow the specific test-pack manufacturer’s instructions for placement, cycle parameters, and interpretation.
Why Is Air Removal Important?
Steam must make adequate contact with the surfaces being processed during steam sterilization.
Air that remains inside a pre-vacuum sterilizer chamber may interfere with steam contact and penetration.
A Bowie Dick test therefore provides a practical method for routinely checking whether the sterilizer’s air-removal system is functioning as intended.
Traditional vs Disposable Bowie Dick Test Packs
Traditional Bowie Dick testing involves preparing a test pack using folded surgical towels and positioning a test sheet in the centre.
Commercial disposable test packs offer a simpler alternative.
