3M™ Comply™ 1250 Chemical Indicator Strips:
A Class 4 multi-parameter chemical indicator (measures time, temperature and saturated steam) printed with a long strip of indicator ink for a wide area of monitoring in the pack. The chemical indicator goes from a gradual, distinct off-white to dark brown/black colour change and has a colour reference standard. The strip can be separated easily at the perforation mark to convert to a short strip. This chemical indicator monitors all 250-272°F/121-134°C gravity and dynamic-air removal (i.e., vacuum-assisted on steam flush pressure pulse) steam sterilisation cycles.
