Formaldehyde Control Indicators should be used inside each pack to show that Low Temperature Steam and Formaldehyde gas (LTSF) have penetrated the pack in a sufficient quantity and for the correct length of time for sterilization to occur.

The control indicator turns from blue to a complete green when adequate sterilizing conditions have been reached.

It is recommended that Browne Formaldehyde Process Detector (Order Code 2402) Spots are placed on the outside of each pack to allow processed and unprocessed items to be identified at a glance.

Note that the spots are not calibrated to be used as an ‘in-pack’ control indicator.

According to ISO 11140-1 class 4.
