Environmentally controlled in vitro incubator

摘要: An environmentally controlled incubator (11) in which the enclosure of chamber (15) strongly attenuates transmission light having wavelengths below about 500 nm for protecting biological materials within from toxic effects short wavelength light. The also includes sensors determining oxygen (47) and carbon dioxide concentration (43) means adding (45) or nitrogen (49) to ambient gas order maintain desired levels oxygen. A thermostatically heater (37) a humidification (31) warm humidify as it is circulated through under control fan (33). airlock (57) provided allow be placed removed chamber.
