What better way to create the ideal in vivo environment, in vitro, than via CO2 incubation? In 1885, Wilhelm Roux kept the medullary plate of a chicken embryo alive for several days in saline solution. Since CO2 incubators became commercially available in the late 1960s, manufacturers have been given the opportunity to improve their incubators and introduce cell culturing to the age of high-tech biotechnology. With numerous options available for most CO2 incubators, it is important to determine
