Activation
After the sterilization cycle, crush the media ampoule with the tool provided or by squeezing the sides of the plastic tube by hand. The unit is properly activated when the media has been released from the ampoule and the spore disc is in contact with the released media.
Labeling
Each unit is labeled with lot number, expiration, manufacturer and species of organism. Unit has a process indicator on it to assist the user in distinguishing an exposed from an unprocessed unit.
Control
The control unit should exhibit a color change to or toward yellow and/or turbidity. If the control unit does not show signs of growth, consider the test invalid.
Test
A failed sterilization cycle is indicated by a color change to or toward yellow and/or turbidity. A test unit that retains its original purple color indicates that sterilization parameters have been met. ExpoSure® is manufactured and tested in accordance with ISO 11138 and current USP.
