BIOLOGICAL CHAMBER APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus suitable for growth of microorganisms under con- trolled atmospheric conditions has a tray member with an open top and a closure member capable of being removably placed over the open top of the tray member. The tray member defines a main chamber therewithin and has means defining a separate open-topped chamber located within the main chamber and extending from the bottom of the tray to adjacent the plane of the open top thereof. This separate chamber communicates with the main chamber through at least one opening when the closure member is in place on the tray. A gas -generating composition can be placed in the separate chamber before the closure is placed on the tray. Thereafter when the cover is in place, gas from said composition can flow from the separate chamber into the main chamber to provide the desired atmosphere in said main chamber. - 1 -
