Prevention of contamination
In servicing for CO
2
incubator, it is important to prevent from contamination.
䠄1䠅㻌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.
䠄2䠅㻌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,
䐟㻌Be sure to wash and sterilize your hands prior to servicing. Use 70䠂 ethanol.
䐠㻌In installing, sterilize the inside wall and shelves after removing shelves, duct, humidifying pan
and so on with 70% ethanol.
䠄3䠅㻌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)-䐠 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 䠄hard䠅 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䠊 Cream cleanser 䛂Gif䛃 䠄Nippon Leva䠅
2䠊 Picasso #SUS300-W 䠄Chemical YAMAMOTO䠅
䠘Picasso has greater capability of clean for rust than Gif.䠚
