An incubator is a specialized piece of laboratory equipment that creates and maintains specific conditions needed for scientific experiments and biological samples. It's like a highly controlled environment chamber that can regulate temperature, humidity, and other factors. Scientists and lab technicians use incubators to grow cells, cultures, and microorganisms, or to study how things develop under precise conditions. In laboratory job descriptions, experience with incubators often means the person knows how to properly use, monitor, and maintain these important pieces of equipment.
