The SteriTec Steam Chart 121 uses top-of-the-line ink that changes from purple to green to provide an integrated response to steam sterilization at 121°C (249.8ºF)to 134°C (273.2ºF) for pre-vacuum or gravity sterilizers operating for 15 minutes or longer.
The Steam Chart 121 has four different timing indicators printed on each strip.
If the first, second and third spots turn green sterilisation conditions were met.
It gives a visible confirmation of the attainment of sterilization conditions at the location within the sterilizer chamber. Lead free, plastic laminated.
