The letters STERILE with EO beside them in a rounded box.
Also known as: STERILE EO, Ethylene oxide sterilised, Gas sterilised symbol, Sterile with EO in a box
STERILE EO says the device was sterilised with ethylene oxide gas, and the method is on the label because it matters: EO leaves residues that are controlled by limit, and a device sterilised this way cannot simply be autoclaved by the user.
Indicates that a medical device has been sterilised using ethylene oxide.
Contexts: Medicine
Names the method rather than only the state, because residual ethylene oxide is a controlled residue with defined limits and because the method constrains what reprocessing is possible.
Contexts: Medicine
Belongs to a family of method-specific marks — EO for ethylene oxide, R for irradiation, VH2O2 for vaporised hydrogen peroxide — which share the STERILE word and differ in the qualifier.
Contexts: Medicine
The word STERILE in capitals followed by the letters EO, enclosed in a rounded rectangular border.
