Interior of a CO 2 incubator used in cell culture. 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.
In practice, the term "cell culture" now refers to the culturing of cells derived from multicellular eukaryotes, especially animal cells, in contrast with other types of culture that also grow cells, such as plant tissue culture, fungal culture, and microbiological culture (of microbes).

Incubation times vary based upon the microbe that requires culturing. Traditional culturing techniques, for example, require less than 24 hours culture time for Escherichia coli but 6–8 weeks for successful culturing of Mycobacterium tuberculosis before definitive results are expressed. [5]
Drawing of the incubator used by Dallinger in his evolution experiments. One of the first to carry out a controlled evolution experiment was William Dallinger. In the late 19th century, he cultivated small unicellular organisms in a custom-built incubator over a time period of seven years (1880–1886). Dallinger slowly increased the ...
The bath is a fundamental product in any laboratory. Over the years, water baths have evolved from basic analog tools to advanced digital machines capable of sophisticated and programmable controls, functions, and capabilities. Key features in water baths often include: Multi-language operation; User-settable limit values
Incubator (culture), a device used to grow and maintain microbiological cultures or cell cultures; Incubator (egg), a device for maintaining the eggs of birds or reptiles to allow them to hatch; Incubator (neonatal), a device used to care for premature babies in a neonatal intensive-care unit
In many laboratory experiments it is good practice to have several replicate samples for the test being performed and have both a positive control and a negative control. The results from replicate samples can often be averaged, or if one of the replicates is obviously inconsistent with the results from the other samples, it can be discarded as ...
