Steam Chemical Indicators are precision-engineered for use in standard steam sterilizing processes. These strips are compatible with 250° F (121°C) gravity steam, as well as 270°F (132°) and 273°F (134°) prevacuum steam cycles.
ISO Compliant
Fully complies with ISO 11140-1 Class 4 standards.
Dual Monitoring
Monitors exposure time, temperature, and steam quality.
Safe Formulation
Lead-free formulation for environmental and user safety.
These indicators provide a consistent color change, making it easy for medical staff to interpret sterilization results accurately. They should be placed inside every pack to ensure the steam has effectively reached the contents.

Frequently Asked Questions
What is a Class 4 Chemical Indicator?
A Class 4 indicator is a multi-variable indicator designed to react to two or more critical parameters of the sterilization process, typically time and temperature.
How should the indicator strips be stored?
They should be stored in a cool, dry place away from direct sunlight and sterilization agents before use to maintain their accuracy.
Can these strips be used in Dry Heat sterilization?
No, these specific strips are designed exclusively for Steam sterilization processes (gravity and prevacuum).
How do I read the results?
The indicator ink will undergo a distinct and consistent color change when exposed to the correct sterilization parameters, providing a clear visual pass/fail signal.
Are these indicator strips safe for medical environments?
Yes, they feature a lead-free formulation and are made from medical-grade paper, ensuring safety for both patients and healthcare providers.
How many strips are included in one box?
Standard packaging for models AQ2140, AQ2141, and AQ6140 includes 250 pieces per box.
