Steam sterilization (autoclaving) of accessories
The accessories listed as compatible with steam sterilization (autoclaving) in
Table 2.1 can be sterilized by steam within the parameters given in Table 2.3.
When steam sterilizing, follow the cleaning, disinfection and sterilization
protocols of your hospital and the sterilization equipment manufacturer’s
instructions.
The results of sterilization depend on various factors such as
how the sterilized instrument was packed or the positioning,
method of placing and loading of the instrument in the
sterilization device. Please verify the sterilization effects by
using biological or chemical indicators. Also follow the
guidelines for sterilization issued by medical administrative
authorities, public organizations or the infection management
sections at each medical facility, as well as the instruction
manual of the sterilization device.
• Do not steam sterilize the endoscope. Steam sterilization
(autoclaving) will severely damage the endoscope.
