ABSTRACT:
A cell culture incubator has a chamber divided into an incubation portion and a control portion. The incubation portion is adapted to contain a cell culture receptacle. A cell culture receptacle agitator is located in the control portion of the incubator and linkage between the cell culture receptacle agitator and the incubation portion of the chamber causes agitation of the cell culture receptacle. A heater in the control portion of the chamber heats air from the external environment and transports the heated air to the incubation portion of the chamber. A wall divides the chamber into the incubation portion and the control portion. The heater may be a forced air heater that provides a positive pressure to the incubation portion of the chamber to reduce contamination in the incubation portion. A nutrient and gas circulation system communicates with the cell culture receptacle in the incubation portion of the chamber. The nutrient and gas circulation system includes a gas source external to the incubation portion of the chamber and tubing provides communication between the gas source, the cell culture receptacle in the incubation portion of the chamber, and nutrient media. A filter in an opening of the incubation portion of the chamber communicates with the tubing to remove contaminants from gas emanating from the cell culture receptacle prior to venting to the external environment.
