  • When the container is labeled.

Such products should be checked in advanced because despite the stainless parts can be sterilized, but the attached parts may not be sterilized. (For example, it is impossible to sterilize parts due to low heat- resistance.)
Please check the product’s thermal resistance or contact our company before you sterile the products like this.
In addition, NITTO’s standard silicon gasket materials ([PQA] [PQB] [PQL]) can be sterilized by steam.

What should we be careful when sterilizing the stainless steel products?

  • Remove the parts that cannot be sterilized.
  • Remove all parts that can be removed to make sure every corner can be sterilized.

Will stainless steel products get rusty after the sterilization?

Insufficient drying after sterilization may cause rusting.

Stainless steel is not non-rusting, but rust-proof metal (not easy to rust), and if conditions for corrosion are met, it will rust.
For example, if water drops are left after sterilization, the container may get stained or become rusty as in the case of normal cleaning procedure, so please dry them thoroughly after sterilization.
