The chemical indicator on the outside of our sterrad cassettes have a slight color change.The cassette's packaging indicator is meant to warn the user of risk of exposure to the sterilant contained within in the event that cassettes casing fails or becomes damaged.The color indicator strip on the side of the cassette package should remain yellow unless the cassette and the sterilant contained within are compromised.User interpretation of the slight color change in the indicator is that the cassette is questionable and should not be used.Manufacturer response for sterilant cassette, sterrad (per site reporter).Asp's technical service rep sent an email with a diagram of the acceptable color change range of the packages indicator.
