A well plate and its supporting devices provide capabilities found in larger fermenters, such as controlling the oxygen level, the pH level, and temperature of the contents of the well. The well plate includes a plurality of wells, each of which can be independently controlled. Apertures in the wells, for example, provide access for a gas supply and sensors within each well provide data relating to, e.g., oxygen and/or pH level in the well. A control system controls the gas supply for each well based on the information provided by the sensor within the well. Similarly, temperature control elements, such as a heater or cooler, is placed in thermal contact with the interior of the well, as is a temperature measurement element. A control system can independently control the temperature of the contents of the well based on information provided by the temperature measurement element for that well.

A closure for a microreactor includes a cap that is configured to be inserted into a well of the microreactor. The cap, or at least a portion of the cap, is compliant so as to form a seal with the well when the cap is inserted. The cap includes an aperture that provides an airway between the inside of the well to the external environment when the cap is inserted into the well. A porous plug is inserted in the aperture, e.g., either directly or in tube that extends through the aperture. The porous plug permits gas within the well to pass through the aperture while preventing liquids from passing through to reduce evaporation and preventing microbes from passing through to provide a sterile environment. A one-way valve may also be used to help control the environment in the well.
