Safety Notices:
This sterilizer is only suitable to sterilize moisture- and heat-resistant medical devices, not
okay for oils and powders, such as petroleum jelly and agar.
This sterilizer cannot be used for sterilization of liquids or liquids sealed with closed containers
(especially glassware), which may cause the containers to burst, endangering the safety of
persons and equipment.
Chloride ion is an important factor causing corrosion of stainless steel. If you use this sterilizer
to sterilize items which contains chloride ions, you must rinse the sterilization chamber with
clean water after each cycle to prevent the deposited chloride ions from corroding the pot and
extending the service life of the equipment.
