Steam Type 4-5-6 Chemical Indicators

WISAS STEAM Chemical Indicators. Multi-parameter indicators have been designed for two or more of the critical parameters. 

They indicate exposure and other selected critical parameters during sterilisation. They have been designed for heat, time and saturated steam control in the steam sterilisation procedure. Thanks to their lamination, they inhibit possible ink transfer. Thanks to the gradual colour change of the indicator, it makes it possible to make comment on the exposure of the procedure. Black which is the reference colour is reached when all critical parameters of the steam sterilisation have occurred. Colour change maintains its stability for a minimum period of six months. It has been designed for internal and external observation.

It does not contain any heavy metals and is not toxic. It is launched to the market as 250 strips/box. There is a lot number and best before date printed on each strip for easy traceability. It is produced in compliance with ISO 11140-1 standard.
