Preventing contamination
To prevent contamination of the chamber, select a suitable installation site.
 Avoid locations with high temperatures or humidity.
Avoid locations with high temperatures or humidity, because of a greater presence of microorganisms in
the air.
 Avoid locations with passers-by or drafts.
Avoid locations near doors, air conditioners, fans, etc., where passers-by or drafts can facilitate the entry of
microorganisms into the chamber.
 If possible, use a cleanroom.
To achieve a better culture, it is recommended that a cleanroom be used if one is available.
 Use clean containers.
The greatest cause of contamination is dirty containers for cultures. Be careful not to get containers or
trays dirty when taking them in and out.
 Keep the chamber clean.
Wipe off any fingerprints. If water spills from the humidifying pan, or if the doors are left open for a long
time, condensation may form on the inside of the doors. If that occurs, wipe off the condensation with a dry
sterile gauze. In particular, clean and disinfect the chamber if the culture medium is spilled. For details,
refer to “ROUTINE MAINTENANCE” on page 86.
 Use sterile distilled water in the humidifying pan.
Always use sterile distilled water in the humidifying pan. Do not use ultrapure water, because it may cause
red rust-like particles in the humidifying pan. Clean the humidifying pan once a month. In some cases, an
antibacterial ingredient may precipitate in the water for humidifying. This is not a malfunction.
 Keep the incubator out of direct airflows from air conditioners or fans.
Cool airflow from an air conditioner may cause condensation and lead to possible contamination.
