Incubator (culture)

In microbiology, an incubator is a device for controlling the temperature, humidity, and other conditions in which a microbiological culture is being grown. The simplest incubators are insulated boxes with an adjustable heater, typically going up to 60-65°C (140-149°F), though some can go slightly higher (generally to no more than 100°C). More elaborate incubators can also include the ability to lower the temperature (via refrigeration), or the ability to control humidity or CO₂ levels.

Most incubators include a timer; some can also be programmed to cycle through different temperatures, humidity levels, etc. Incubators can vary in size from tabletop to units the size of small rooms.

Incubators also contain certain features such as the shake speed, measured by revolutions per minute. As for temperature, most commonly used is approximately 36-37 degrees Celcius. This is also typically your body temperature. Most bacteria grow well under such conditions.
