Abstract:
A system (10) for mixing a liquid solution or suspension includes a support housing (14) bounding a compartment and a collapsible bag (12) disposed within the compartment. A mixer (18) is disposed within the collapsible bag while a sparger (59) delivers a gas to the lower end of the collapsible bag. A gas outlet line (51) extends from an upper end of the collapsible bag to a condenser assembly (16). A gas exhaust line and a fluid collection line both extend from the condenser assembly.
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 fluid manifold system includes a manifold having at least portions of opposing flexible sheets welded together to form a fluid flow path therebetween, a fluid inlet communicating with the fluid flow path. A plurality of receiving containers are in fluid communication with the fluid flow path of the manifold, each receiving container bounding a compartment. The receiving containers can be formed integral with the manifold by welding together a second portion of the opposing flexible sheets or can comprise separate containers that are coupled to the manifold.
Abstract:
A polymeric, multilayer, film structure includes a polyester elastomer layer (COPE) and a thermoplastic polyurethane layer (hereinafter "TPU"). Multilayer film structures that include COPE and TPU have been found to have good properties for use in making thin film bags, containers, and flexible tubing.
Abstract:
The present invention relates to a stirred-tank reactor system and methods of preparing such systems. The present invention further encompasses the use of the stirred-tank reactor system as a disposable bioreactor and in kits with disposable elements.

Abstract:
A system for forming a fluid connection includes a first connector (12) and a second connector (14). Both connectors include a tubular body (18,18') having a membrane (19,19') mounted on a distal end (27) thereof. A support member (16) or other fastener (214,220) facilitates the coupling of the connectors together so that the membranes are abutted together. Radiant or other form of energy is applied to the abutted membranes so as to sterilize the membranes and melt the membranes so that a passage is formed therethrough.
Abstract:
A container assembly (13) includes a flexible bag having an interior surface bounding a chamber (40) and an opposing exterior surface, the bag having a top end wall (48), a bottom end wall (50), and an encircling sidewall (42) extending therebetween, the bottom end wall including a first polymeric sheet (60) overlying a second polymeric sheet (66). A first weld line welds the first polymeric sheet to the second polymeric sheet, the first weld line bounding a first sparging area formed between the first polymeric sheet and the second polymeric sheet. A plurality of first perforations are formed through a portion of the first polymeric sheet that overlies the first sparging area so that gas can pass from the first sparging area, through the first perforations and into the chamber of the bag.
Abstract:
A tube port includes a tubular first stem having an interior surface and an exterior surface extending between a first end and a longitudinally spaced apart second end. The interior surface bounds a passage that longitudinally extends through the first stem. The tube port also includes a flange encircling and radially outwardly projecting from the first end of the first stem. The flange and the first stem are integrally formed as a unitary member comprised of a flexible elastomeric material having a durometer on a Shore A scale with a value of less than 90.
