Abstract: A single use wall pass-through system having a fixed wall part attached through an opening in a wall and connected by at least one mounting flange. The fixed wall part includes clamping flanges used to provide a sealed connection between the fixed wall part and the hose or tube which carries the material from an outside area into another area defined on the inside of the wall. A combination gasket and clamp plate formed as one piece connects to the clamping flange via a clamping ring. The transfer hose and the combination gasket and clamp plate are preferably disposable.

A gasket is used along with a clamp plate for connection to the clamping flange via a clamping ring. The clamp plate can be two pieces separated by a dividing line and the clamp plate hose opening intersects the dividing line. The transfer hose and the gasket are disposable. The clamp ring and clamp plate can be re-used.

Abstract: A diaphragm valve (1) comprising a valve body (2); a diaphragm (12) which is sealed to the valve body (2) to define a flow passage (9) which extends between an inlet port (7) and an outlet port (8), both defined by the valve body (2); and an operating mechanism secured to the valve body (2) for moving the diaphragm (12) into sealing engagement with a seat (11) provided on the valve body (2) in order to close the flow passage (9) to fluid flow. The valve body (2) and diaphragm (12) are formed as a disposable assembly having a relatively less flexible region which forms a valve seat (11) and a relatively more flexible region (12) which forms the diaphragm which may be forced into engagement with the valve seat (11) to close the flow passage (9) to fluid flow, and a housing (3) is provided for mechanically supporting the region of the valve body in which the seat area is defined.

Abstract: A system for mixing a liquid solution or suspension includes a collapsible container having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution or suspension. A mixer is enclosed within the compartment of the container. A shaft has a first end connected to the mixer within the compartment of the container and a second end disposed outside of the compartment, the shaft being selectively movable relative to the container. A gas pathway extends from a portion of the shaft disposed outside of the container to a portion of the shaft or mixer disposed within the compartment of the container, the gas pathway extending through at least a portion of the shaft.

Abstract: A method for mixing a solution includes positioning a collapsible container within a chamber of a substantially rigid tank. The collapsible container bounds a compartment. A mixer is disposed within the compartment of the container. Two or more components are fed into the compartment of the container. At least one of the components is a liquid. The mixer is raised and lowered within the compartment of the container so as to mix the components.
