Sterile Confirmation Strips, pack of 20

These strips incorporate a steam/temperature sensitive chemical reagent contained in a transparent laminate.  It provides a visual accept/reject readout to confirm that

• Steam has penetrated to the point of placement

• Sufficient exposure conditions have been met to achieve sterilisation.

The image on the left shows an unexposed strip (top) and a strip that has been exposed to sterilisation (below).  Note that for the exposed strip, the black indicator has migrated into the "Accept" zone.
