True Indicating Bowie Dick (BD) Test Packs contain no lead or other toxic heavy metals and are made of recyclable materials. The Test Packs contain an internal Indicator sheet which is used to evaluate the efficacy of air removal and steam penetration in pre-vacuum sterilizers. A uniform color change to Pink of the internal Indicator sheet provides evidence that the sterilizer has successfully removed air and can allow steam to penetrate a load placed in the chamber.
The Test Packs are for use in pre-vacuum steam sterilizers operating at 121°C and 134°C. The Test Packs simulate a 7kg cotton pack according to ISO 11140-4 Type 2 and EN 867-4 Class B.
Monitor For: Pre-vacuum Steam Sterilizers
Test Pack Dimensions: L: 105mm x W: 65mm x H: 4mm
Packaging: 50 Test Packs / Box
Chemical Indicator Initial Color: Blue
Signal Color: Pink
The Bowie Dick Test Pack detects the presence of residual air in pre-vacuum steam sterilizers operating at
134°C for 3.5 or 121°C for 15 minutes. The internal Indicator sheet will demonstrate a uniform color change
from Blue to Pink when proper conditions as identified in ISO 11140-4 for Sub-atmospheric pulsing have
been met. If insufficient steam penetration occurs during the exposure cycle, the Indicator sheet will yield
an inconsistent color change which is not uniformly Pink.
