Product Description
This listing is for the 3M™ Attest™ Steam Chemical Integrator (REF 1243 / catalog 1243A), a Type 5 (ISO 11140-1:2014) integrating chemical indicator strip sized about 2" × 3/4" (≈5.1 × 1.9 cm).
- The strip uses moving-front ink visible through a narrow window; when process conditions inside a pack are adequate the ink front travels from the red 'REJECT' zone into the green 'ACCEPT' zone.
- The indicator is intended as an internal pack control monitor to help determine whether steam sterilization conditions were reached inside individual instrument packs.
- The product is supplied commercially in bulk (catalog 1243A is commonly sold as 500 integrators per bag).
- The integrator is labeled on the face with 'STEAM Type 5' and 'REF 1243' (the supplied photograph shows a single strip bearing REF 1243).
- Manufacturer documentation identifies these strips as correlating with performance of a biological indicator across multiple time/temperature relationships and lists compatibility with standard steam sterilization cycles (121–135°C / 250–275°F).
Buyers should check lot/expiry printed on the sealed pack on delivery and follow local facility policies: chemical integrators are a process indicator and are not a substitute for biological indicator testing where required. Note: manufacturer technical literature lists shelf-life values that vary by document and market (see warnings).
