Has anyone ever seen a comparison of the various steam indicators available on the market? We are using one now that will turn if placed in an autoclave, door open, for 30 minutes. Even though instruments should never be placed in the autoclave prior to being "ready to run", it happens. The company in question states that this color change cannot take place... Malarky!
In order to reduce the chance of accidentally using unsterile instruments we would like to find a better alternative.
Input would be appreciated.
