How long will items stay sterile inside the Electric Steriliser?

Sterilised products kept in an unopened Steriliser stay disinfected for up to 48 hours. To maintain this disinfection period, the number of items sterilised together must not exceed the maximum quantities listed in the product charts. For a 24-hour disinfection effect, higher quantities of bottles can be sterilised at once. (Pages 3–4)
