Publication number: 20230358471Abstract: Provided is a multi-part lyophilization container for lyophilizing a fluid, storing the lyophilizate, reconstituting the lyophilizate, and infusing the reconstituted lyophilizate into a patient, including a method of using same. The container includes a front surface, a back surface, a non-breathable section including a port region, a breathable section including a breathable membrane, and a peelable region including a peelable seal encompassing a boundary between the non-breathable section and the breathable section. The method includes inputting a fluid into a non-breathable section of the container, freezing the fluid, applying, in a lyophilization chamber, vacuum pressure, opening the peelable seal using a pressure differential, applying heat energy, sublimating the fluid and creating a temporary occlusion in a peelable region of the container.Type: ApplicationFiled: July 11, 2023Publication date: November 9, 2023Inventors: Kestas P. PARAKININKAS, Eric T. HANSEN, Kirk L. WEIMER, Nathaniel T. JOHNSON, Dennis J. HLAVINKA

Patent number: 6136724Abstract: An apparatus and method for performing multiple wet processing steps on objects placed within a sealed chamber. The apparatus include a sealable chamber, at least one processing tank within the chamber, and preferably also includes an intrachamber robot configured to move objects to be treated within the chamber. Preferred embodiments utilize at least two processing tanks within the chamber. During use of these exemplary embodiments, objects to be treated are placed within the sealed chamber and the chamber is sealed to create a sealed interior environment. The objects are immersed in a first treatment fluid which is in a first one of the tanks, and then carried by the intrachamber robot from the first to the second tank where there are immersed in a second treatment fluid in the second tank. The objects may be moved back and forth between the tanks as needed in order to complete the process being performed. After processing is complete, the chamber is unsealed and the objects are removed from the chamber.Type: GrantFiled: February 18, 1998Date of Patent: October 24, 2000Assignee: SCP Global TechnologiesInventors: Eric T.
