Abstract

A culture bottle assembly has a container divided into two compartments by a flange. A closure and flexible septum seals the container from the outside environment. A frame inside the container is moveable between two positions. In one position the two compartments are sealed from each other, and in the second position fluid communication exists between the compartments. The frame has an elongated member and a skirt. The skirt engages the flange to form a seal. Downward force in the elongated member causes the skirt to flex. Cooperating means create a gap between the skirt and the flange when the skirt flexes. The flexible septum covers the elongated member thereby allowing force to be applied to the elongated member without opening the container. A solid media holder has trays for holding solid media in the upper compartment.
