A bacteriological incubator is an essential laboratory device used to provide optimal environmental conditions for the growth, maintenance, and study of microorganisms. The principal of a bacteriological incubator is based on maintaining a controlled temperature, humidity, and sometimes CO₂ concentration, which are critical factors for microbial growth. Most microorganisms have specific temperature ranges in which they thrive, such as mesophiles at 20–45°C, psychrophiles below 20°C, and thermophiles above 45°C.
