  • Patent number: 11156298
    Abstract: A valve assembly used in a manifold system fix processing fluid samples includes a body, a valve member, and a coupling assembly. The body defines a fluid passage and a valve passage in communication with the fluid passage and receiving at least a portion of the valve member therein. The valve member is selectively movable over a range of travel between an open position, in which fluid can flow through the fluid passage, and a closed position, in which the valve member occludes the fluid passage. The coupling assembly includes a coupling member and a retention lug. The retention lug is connected to one of the body and the coupling member. The other of the body and the coupling member defines a lug raceway configured to removably receive the retention lug therein to removably mount the coupling member to the body with the valve member being movably retained therebetween.

  • Publication number: 20210199679
    Abstract: A buffer management system includes at least one workstation configured to support a supply of concentrated buffer solution and an inline dilution skid having a manifold and at least one workstation to support delivery of diluted (surge) buffers from the inline dilution skid. The latter workstation also serves to supply ready-made (diluted) buffers to a bioprocessing unit. The manifold is in fluid communication with the supply of concentrated buffer solution and is adapted to be placed in fluid communication with a source of water for injection (WFI). The inline dilution skid is configured to variably mix the supply of concentrated buffer solution and the source of WFI to obtain a range of diluted buffer solutions. Processes for automatically identifying the arrangement of buffer solutions in a bioprocessing application use signals from various sensors to identify the fluid connections between components of the system.

  • Publication number: 20210197189
    Abstract: A buffer management system includes a supply of concentrated buffer solution, an inline dilution skid having a manifold in fluid communication with the supply of concentrated buffer solution and a control unit configured to operate the dilution skid to selectively dilute the supply of concentrated buffer solution in the manifold with a source of water for injection (WFI), and a biocontainer assembly. The biocontainer assembly includes a biocontainer bag defining a storage volume and a fill level sensor configured to generate a fill level signal indicative of the amount of material within the storage volume of the biocontainer bag. The biocontainer bag is in fluid communication with the manifold of the dilution skid for storing diluted buffer solution therein. The fill level sensor communicates the fill level signal to the control unit of the dilution skis, which uses it to manage the operation of the dilution skid.
