Bowie Dick Test Pack makes the operator a right control of the autoclave and verify possible defects during Bowie Dick's cycle. Bowie-Dick test packs should be used daily, especially after a sterilizer is installed, relocated, after sterilizer malfunction, after sterilization process failures, and after any major repairs of the sterilizer.
Operation Condition:  134ºC, 3.5minutes
Single use Bowie Dick pack is characterized by the most reliable test such as: 
1. Point out the presence of air leaks in the autoclave immediately and accurately; 
2. Nontoxic ink and completely recycled materials;
3. Color Change: yellow to brown
4. CE certificated
5. Lead free 
Notices:
1. The saturated stream pressure should reach to 0.4Mpa - 0.6Mpa if air is supplied through pipe; and non-uniform color changes may be observed if the pressure is lower than 0.3Mpa;
2. As for the pre-vacuum steam sterilizers or high vacuum autoclave with pulsing systems with air supply by pipe, the time of stopping air supply should longer than 2 days; and air-removal process should be done before re-using, or else, large amount of aqueous vapor existing in saturated stream may cause difficulty in cool air removal and wet pack, which will result in incapability of demonstrating test results due to wet B-D test paper.
