3M Attest Vaporized Hydrogen Peroxide Tri-Metric Chemical Indicators ISO Type 4, 0.75" x 2" (1.9 x 5.1 cm)

3M™ Attest™ Vaporized Hydrogen Peroxide Tri-Metric Chemical Indicator (1348) is the first FDA-cleared multivariable chemical indicator for vaporized hydrogen peroxide (VH₂O₂) sterilization. Designed to independently monitor three critical variables — time, temperature, and VH₂O₂ concentration — this indicator provides the highest accuracy and precision in detecting sterilization failures across a range of systems and chamber designs.

• Triple-parameter monitoring: Simultaneously evaluates time, temperature, and hydrogen peroxide concentration for comprehensive sterilization assurance.
• Clear visual readout: Color changes to pink when proper exposure parameters are achieved, providing instant verification of sterilization success.
• High sensitivity and reliability: Detects performance variations faster and more accurately than standard Type 1 or Type 4 indicators.
• Validated VH₂O₂ compatibility: Suitable for use with sterilizers from STERIS® and ASP™ Advanced Sterilization Products.
• Compact strip format: 1.9 cm × 5.1 cm (0.75" × 2") for convenient placement in trays, packs, and loads.
• Regulatory compliance: ISO Type 4 indicator cleared by the U.S. FDA for vaporized hydrogen peroxide sterilization monitoring.

Packaging: 250 Indicators/Bag, 4 Bags/Case (1,000 Indicators/Case)

Recommended for monitoring vaporized hydrogen peroxide sterilization cycles in healthcare and laboratory environments where high-precision, multi-variable chemical verification is required.
