Abstract: A system for sterilizing or bioburden-reducing a filter device includes a breathable microbial barrier, a filter device, and a tubing arrangement. The tubing arrangement may be coupled to at least one opening of the filter device. The tubing arrangement may include an aseptic connector, a sealable component, and a port, all of which are in fluid communication with one another. The sealable component may be disposed in the tubing arrangement between the at least one opening of the filter device and the aseptic connector. The sealable component may be reconfigurable between an open configuration, which facilitates the entry of a sterilization vapor into the tubing arrangement and the filter device when subjected to a sterilization or bioburden reduction process, and a closed configuration, where the tubing arrangement is sealed from a surrounding environment. The breathable microbial barrier may at least partially enclose the port of the tubing arrangement.

Abstract: A depth filtration device for the clarification of biological fluids including a composite depth filter media having a nonwoven first layer integral with a second layer containing a polyacrylonitrile (PAN) fibers, a filter aid, and a wet-strength resin. The depth filter media exhibits increased binding capacity for soluble impurities such as DNA and host cell proteins from biological/cell culture feedstreams during secondary clarification and low-level impurity clearance of harvested cell culture fluids, such as those used for the manufacture of monoclonal antibodies. The depth filter media additionally exhibits significantly lower flushing requirements, resulting in lower levels of organic, inorganic and bioburden extractables released, high dirt holding capacities and good chemical and/or radiation resistance.

Abstract: A valve having a body having a first section and a second section; an extended flange attached to the second section of the body or disposed as an integral part of the second section of the body; an elongate bore extending through the body and having a proximal end and a distal end; a longitudinally displaceable plunger disposed in and extending along the bore, the plunger having a proximal end and a distal end and having a first position displaced toward the distal end of the bore and a second position displaced toward the proximal end of the bore; a diaphragm seal attached to the proximal end of the plunger and sealing the bore at the proximal end thereof; a gland seal sealing the bore at a location intermediate the diaphragm seal and the distal end of the bore; the plunger extending through and being sealingly secured to the gland seal; a fluid transfer opening in the bore between the diaphragm seal and the gland seal; longitudinal displacement of the plunger moving the diaphragm seal to open the bore, the gland seal stretching to accommodate the displacement of and maintain a seal about the plunger, a fluid flow path being established between the open proximal end of the bore and the fluid transfer opening, wherein longitudinal displacement of the plunger towards its first position moves the diaphragm to open the bore. The valve further comprises an extended flange having a surface that is approximately coplanar with a surface of the second position when the plunger is displaced toward the proximal end of the bore, creating a zero dead leg position.
