Prevention of contamination
In servicing for CO
2
incubator, it is important to prevent from contamination.
䋨1䋩㩷More than 90% of contamination in CO
2
incubator is caused by mold. Mold is a kind of
true fungi, it has high increasing power under high temperature and high humidity.
Accordingly, it is easy for mold to increase inside CO
2
incubator. Those increased mold
eat up culture (mainly animal cell), eventually precious test sample will be killed. Cell that
is independent from ecosystem is also independent from immune system, it has no
immunity against all.
䋨2䋩㩷Precautions for mold increasing
There are many cases that mold multiply by eating fat on the fingers as a source of
nutrient in CO
2
incubator.
Therefore,
㽲㩷Be sure to wash and sterilize your hands prior to servicing. Use 70䋦 ethanol.
㽳㩷In installing, sterilize the inside wall and shelves after removing shelves, duct,
humidifying pan and so on with 70% ethanol.
䋨3䋩㩷In the case that mold has already multiplied.
Sterilize the interior (walls) and shelves with 70% ethanol after removed all items from
the chamber as same as (2)-㽳 above.
And you should sterilize again after 24 hours once sterilized, when the root of spore is
geminated, because it is too difficult to remove spore of mold. Repeat sterilization is
effective.
In general, stainless steel is known that it is not easy 䋨hard䋩 to rust.
However depends on the conditions, rust might generate.
When you remove rust, we recommend the following agents.
Besides, the surface may become foggy.
Recommended agent:
1䋮 Cream cleanser 䇸Gif䇹 䋨Nippon Leva䋩
2䋮 Picasso #SUS300-W 䋨Chemical YAMAMOTO䋩
䋼Picasso has greater capability of clean for rust than Gif.䋾
