Cell Culture Incubator Humidity

An incubator is a device used to grow and maintain microbiological cultures or cell cultures the incubator maintains optimal temperature humidity and other conditions such as the co 2 and oxygen content of the atmosphere inside.

Cell culture incubator humidity.

If you use tissue culture plates or dishes the incubator must be humidified to prevent evaporation. The average humidity over land is quite low whilst humidity inside the incubator must always be 100 saturation. Typical temperature settings range from 4c to 50c and co2 concentrations run from 0 3 to 19 9. As such setting incubator oxygen to 3 has been dramatically shown to increase cell proliferation when compared to those cultured in 20 oxygen.

Evaporation leaves too high concentrations of salts minerals etc resulting in toxicity and cell death. The heracell vios 250i co2 incubators provide a premium clean room compatible solution where cultures can grow in a controlled protected environment. Naturally easy to clean no special handling required copper surfaces provide long service life and are safe for cultured cells. Humidity of 85 95 limits evaporation of water from the media.

Some incubators have a pan of water in them to humidify the atmosphere. In a cell culture incubator balanced growth media provide moisture and nutrients for cells. Manipulating relative humidity in cell culture. 6 high humidity ideally at least 95 is also important for efficient incubation.

When humidity drops below 95 for an extended period water will evaporate from the medium and will negatively. The relative humidity for tissue culture incubators is usually 95 helping to prevent evaporation of culture media. Other incubators have an automatically regulated humidity. It is generally accepted that to create an environment conducive to cell growth a co 2 incubator is used to provide a controlled atmosphere with a temperature of 37 c 5 co 2 concentration and 95 relative humidity rh.

Incubators are essential for much experimental work in cell biology microbiology and molecular biology and are used to culture both bacterial and eukaryotic cells. The most important thing however is a constant co2 supply to the incubator since nearly all cultures are kept by means of a co2 hco3 buffer system. Well above all a constant and high humidity ideally at least 95 as well as fast recovery times after the door has been opened. A cell culture incubator is designed to maintain a constant temperature and high humidity for the growth of tissue culture cells under a co2 atmosphere.

If the co2 supply should fail just for a short time the ph value in the culture medium. More cell culture professionals are choosing co 2 incubators with 100 pure copper interiors.
