Preventing Contamination - Phcbi MCO-230AICL-PE Operating Instructions Manual

Preventing contamination

To prevent contamination of the chamber, select a suitable installation site.
 Avoid locations with high temperatures or humidity where the air may contain more
microorganisms.
 Do not place the incubator near doors, air conditioners, fans, etc, where draughts and passage of
bodies may increase the risk of microorganisms entering the chamber.
 If possible, use a cleanroom.
 Use clean containers. Dirty containers are the greatest cause of contamination 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. Wipe off
condensation with a piece of dry sterile gauze. In particular, clean and disinfect the chamber if the culture
medium is spilt.
 Use sterile distilled water in the humidifying pan. Do not use ultrapure water, which may cause red
rust-like particles in the humidifying pan. Clean the humidifying pan once a month.
 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.
