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 (10 L or more) and narrow mouth
Advisory Note
When sterilizing liquid in a container with large capacity (10 L 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 it may be pinched between
the chamber opening and the cover packing, resulting in
trouble with the product.
