Sterilization Objects
Sterilization of equipment, etc.
When sterilizing only containers such as beakers, flasks and test
tubes, place them with their openings facing downward or lay
them on their sides.
If the containers are placed with their openings facing upward, it is
hard for air to sufficiently escape from the container and for steam
to sufficiently penetrate inside, thus resulting in incomplete
sterilization.
Sterilization for waste disposal
• When sterilizing waste, pour about 300 ml of water into the
sterilization bag and sterilize the waste with the bag open.
Sterilizing without water in the bag or with the bag closed may
result in incomplete sterilization. An error message may appear
due to expansion of the air remaining in the bag.
If the container containing the sterilization objects is broken and
the content spills over, sterilize them in the same manner as
stated above before discarding.
• When sterilizing the culture medium in petri dish for disposal,
uncover the petri dish. If the sterilization is performed with
covered petri dish, an error message may appear due to
expansion of air remaining in the petri dish.
Sterilization using container with large capacity (10L or more) and narrow mouth
Advisory Note
When sterilizing liquid in a container with large capacity (10L or
more) and narrow mouth, fill the container 50% or more of its
capacity.
When a small amount of liquid is sterilized in a container with large
capacity and narrow mouth, the pressure builds up during
sterilization and steam may burst out from the pressure safety
valve. For sterilization of small amount, use a container with large
capacity and large mouth or replace it with a small-capacity
container suitable for the quantity of liquid.
On sterilization bag
When using the sterilization bag, be sure to put it in the stainless steel
basket included with the product and set it in the chamber for
sterilization. If the sterilization bag is put directly in the chamber, it may
block the temperature sensor or holes in the chamber to raise the
pressure and an error message may appear. Be careful not to allow
the sterilization bag to be pinched between the opening of chamber
and the cover packing. Otherwise, steam may result in trouble.
