A portable incubator having an open top jar which is closed by a lid secured to the jar by a releasable clamp. The lid has a conduit on its upper surface, the conduit communicating with a hole through the lid and provided with a pair of opposed ends. There is a valve for each end of the conduit, respectively. A holder for culture dishes can be moved into and out of the jar, the holder being formed by a number of rigid straps arranged to form a side opening in the holder so that the culture dishes can be put into the holder and supported on the bottom of the same. A hand-held, hand-actuated vacuum pump can be carried with the jar and has a flexible tube connecting it to one end of the conduit so that the interior of the jar can be evacuated in a short time. The opposite end of the conduit is adapted to permit a gas to be injected into the jar under pressure after the jar has been evacuated. The jar can be placed in an operative position in a housing having a top wall provided with an opening for receiving the jar. A flange on the upper end of the jar engages the top wall to limit the inward travel of the jar into the housing. In one form of the invention, heater means is provided on the inner surface of the housing. In another form, a cylinder extending downwardly from the opening in the top wall is adapted to receive the jar and has a heater coil surrounding it.
