●

For sterilization of liquid, set a sterilization time longer than usual by taking delay time into

account and by referring to the table below.

Ex. :

When there is 3 liters of water in a flask, it takes nearly 30 minutes (delay time) for

temperature of water in the container to reach a set sterilization temperature after

temperature in the chamber reaches the set value. You should set a sterilization time

30 minutes longer than usual to cope with this delay time.

Set sterilization time (50 minutes)

= Delay time (30 minutes) + Sterilization time (20 minutes)

When a dressing drum is used, it takes several hours for the temperature in waste disposal bag

to reach the set temperature after the temperature in the chamber (displayed temperature)

reaches the set temperature (delay time).

If there is approx. 300 ~ 500 milliliters of water in the waste disposal bag, steam is generated in

the bag and drives the air out. This will significantly reduce the delay time at the time of

temperature rise. Refer to the table below and take this delay time into account when setting

the sterilization time.

The delay time will be shortened when a perforated dressing drum is used.
