How to carry out Bowie & Dick test

1)Preheat autoclave (sterilizer) before the test.
2)Prepare the indicator for your Bowie & Dick test.
*”Bowie & Dick test sheet” is literally the sheet itself and can’t be used as it is. Please insert the sheet into the center of the test pack before the test.

How to assemble Bowie & Dick test pack
1)Fold a surgical towel into 24cm * 30cm size and pile the folded towels to between 25-30cm high.
2) Insert the Bowie & Dick test sheet to the center of the pile of towels, and wrap it gently with muslin or nonwoven sheet.

*BD box and AC test pack are pre-assembled and ready to use.


3)Check if the autoclave chamber is empty (no load). Put the test packs horizontally near the chamber door, just above the drain, on the near side of sterilization tray base.
4)After pre-vacuum cycle, run the Bowie & Dick cycle at 134℃ for 3.5 min. After the cycle, take the test pack and unpack it to interpret the color changing results of the indicator.
5)An even color-change means the successful test cycle, but if there’s the area with no color change, it means that an air pocket was formed and left at the site of uneven color change. In the case, please adjust the sterilizer and check the cycle conditions.
6)Carry out this test every day, before starting the first sterilization cycle of the day.
