Abstract:
A testing method that includes the steps of evacuating air from a container to a negative atmospheric pressure, the container being a collapsible, flexible container, and comprising at least two opposing flexible walls, wherein a surface of at least one of the walls internal to the container comprises a plurality of channels or recessed features on said at least one wall and monitoring a mass flow or a state of vacuum so as to determine the integrity of the container. The container can be of any size or conformation, with or without attached fittings.
Abstract:
A device for storing, transporting and/or handling a liquid or liquids and methods for using the device are described. The device is suitable for use with sterile or aseptic liquids, particularly with large liquid volumes such as 10-1000 liters or more, and avoids the need for bags, bins and carriers commonly used for storing and transporting large volumes of liquids. The device comprises a coiled tubing. The coiled tubing can be loaded onto a spool to support the coiled tubing. The tubing can be filled, sealed, stored and transported in a more robust manner than previously achieved with bags, bins and carriers.
Abstract:
A system and method for measuring integrity of flexible containers is disclosed. The system uses a low mass flow transducer to monitor the flow of fluid into the flexible container. Based on this flow rate, the existence of an orifice in the flexible container may be detected. The system also includes a second flow path to the flexible container to allow for faster fill times. Greater flow rates are achieve through the use of a second high mass flow transducer or a calibrated bypass path. These alternate paths allow greater flow rates until the flexible container is determined to be nearly full, at which point all flow passes with the low mass flow transducer.
Abstract:
A collapsible, flexible bioprocessing container, the container comprising at least two opposing flexible walls, wherein the surface of the walls internal to the container comprise raised areas, the raised areas are surrounded by a plurality of lowered channels on said walls and the channels being interconnected.

Abstract:
A sterile to sterile connection device comprising a connector and one or more coupling devices. The connector has body portion which has two openings sealed from the environment so as to form a sterile environment within the connector. At least one of the openings being sealed from the environment by a sterile barrier plug. The connector also has a port capable movement within the body of the connector to at least an open and a closed position. The coupling device is formed of a body having two openings and a stem having a bore through at least a portion of the stem. The stem is contained within the body and capable of moving at least linearly through the body between a first and second stem position. One of the openings of the stem is sealed from the environment by a sterile barrier plug and the other is sealed to a presterilized component. The coupling device opening containing the sterile barrier plug is attached to either the inlet or outlet of the connector.
