STEAM - Class 4 - Multiparameter Chemical Indicators for Steam Sterilization

STEAM Class 4 multiparameter chemical indicators are dedicated to professional control of steam sterilization processes. Specially selected for use in medical facilities, dental clinics, beauty salons, tattoo studios, and the podiatry industry, these indicators are available at autoclaves.shop. Our products are carefully chosen to ensure maximum safety and full compliance with the latest standards and technical requirements.

Class 4 chemical indicators, compliant with ISO 11140-1:2014 Type 4 and EN 867-1, enable effective and precise control of the sterilization process. Each indicator comes in the form of a paper strip with a perforation for easy splitting into two shorter strips. The blue test substance along the entire strip ensures clear result interpretation—after a correctly performed sterilization process, the color changes distinctly from blue to black. This color shift is an unambiguous confirmation of both process effectiveness and steam penetration at the indicator’s location.

STEAM Class 4 indicators are completely safe—free from lead and other heavy metals. Their patented manufacturing technology makes them non-toxic and environmentally friendly. They are designed for sterilizing metal instruments, porous materials, rubber, plastics, and cotton textiles.
