An incubator is an isolated storage place that is used for cultivating bacteria. The incubator maintains optimal temperature of the atmosphere inside. Incubators are essential for a lot of experimental work in cell biology, microbiology and molecular biology and are used to culture both bacterial as well as eukaryotic cells. The simplest incubators are insulated boxes with an adjustable heater, typically going up to 60 to 65 °C (140 to 150 °F), though some can go slightly higher (generally to no more than 100 °C). The most commonly used temperature both for bacteria such as the frequently used E. Coli cells is approximately 37 °C, as these organisms grow well under such conditions. They also need a circulation system for equal distribution of heat in the box.
We made a simple incubator that maintains a temperature of 37 °C.
