  • Publication number: 20090311776
    Abstract: The present invention is a disposable bioreactor formed of molded plastic. The bioreactor is presterilized and has a top and body sealed to each other. One or more ports are formed in the top and side of the housing. Preferably at least one port is below the liquid/air level for the housing. The one or more ports that are below the liquid/air interface level may be used as sampling ports or access ports for probes or drains or supply ports for liquids or gases. The bioreactor provides a direct retrofit for the existing glass or steel assembly that utilizes the existing support structures and controls. The molded design overcomes issues of discontinuity, dead spots and the like due to its fixed dimensions that are built in by the molding process. Reproducible probe and other equipment location is also guaranteed through the use of the molded port features. The molded plastic allows for greater flexibility in material selection to reduce or eliminate lipid or cholesterol binding.

  • Publication number: 20090220294
    Abstract: A connector is provided for connecting a flexible conduit with a second conduit having a barbed outer surface. The connector accommodates the end of the flexible conduit and the end of the second conduit in a manner which prevents removal of the flexible conduit and the second conduit from the connector. Optionally, the connector has a ring that may be used to apply additional pressure and security to the outer surface of the flexible conduit. additionally, the connector may have a wireless enabled communication and optionally, memory device such as a RFID tag attached or affixed to it.

  • Publication number: 20050280178
    Abstract: A method is disclosed for making a substantially flat filter plate comprising a substantially flat polymer, preferably thermoplastic, frame and substantially flat filter material seated fixedly therein. The method is characterized by its reduced exposure of the filter material to adverse mechanical stresses resultant of polymeric frame formation and curing. Toward such end, the substantially flat polymeric frame is formed in at least two separate steps, in the course of which said substantially flat filter material is incorporated. The portion formed first serves as a mechanical restraint, insulating the later incorporated filter material from any propensity of the second “embedding” portion to shrink or otherwise warp during its formation.
