Abstract: Bioreactors suitable for housing a predetermined volume of culture medium comprising a plurality of containers of approximately equal internal volume in which the culture medium resides, wherein the predetermined volume of culture medium is retained in approximately equal amounts within each of the plurality of containers during operation of the bioreactor, and wherein the internal volume of each container is selected so that the amount of culture medium in each container exceeds 50 vol. % of the container internal volume during operation of the bioreactor, and related methods of use.

Abstract: Reactors that allow mixing and gasification by converting the entire floor of the reactor vessel to a sparge filter is described.

Abstract: A septum is positioned within a disposable vessel and defines a lower chamber and an upper chamber. The septum includes a plurality of apertures that provide fluid communication between the upper chamber and lower chamber. Compressed gas is introduced in the lower chamber to produce fine bubbles rising up throughout the vessel to produce a mixing and gasification needed for the growth of a biological culture and manufacture of a biological product in a nutrient medium. Adding a binding resin to the upper chamber allows harvesting, separation and purification of biological products in the reactor as a single unit operation.

Abstract: A pair or receptacles capable of housing an emitter probe and a detector probe installed inside a bioreactor to monitor the properties of the nutrient media without contacting the nutrient media.

Abstract: Single-use closed bioreactors with recirculating exhaust gas that can be operated in an uncontrolled environment are reported for the manufacturing of biological products using genetically modified biological cultures that produces carbon dioxide or that requires carbon dioxide in their metabolic process.

Abstract: Stationary bioreactors and mixing vessels fitted with single-use flexible bags utilizing wave hydrodynamic principle are described for use in every type of biological process and products.

Abstract: A method and an apparatus for separating suspended matter from liquid includes a concentrator filter that draws the liquid out of the suspension while the filter kept unblocked by a sparging filter that allows scrubbing of the concentrator filter by gas bubbles. This invention can be used to replace cross-flow filtration and centrifugation in the bioprocess industry and to reduce the volume of suspensions to concentrate the yield of the end product in the chemical industry.

Abstract: A buoyant device containing chromatography media performs the function of protein harvesting replacing the steps of cell separation and volume reduction; the device can be loaded into columns for further purification.

Abstract: Pressurized hermetically sealed bags disposed inside a cylindrical support and containing a septum with variable density of porosity and dividing the bag into two chambers are used to provide optimal mixing and gasification of nutrient media to grow a variety of biological cultures, particularly the cell cultures to produce a multitude of pharmaceutical and biotechnology products in a disposable system.

Abstract: A chromatography column that captures components in a process liquid in a free flow state and allows elution in steps is described.

Abstract: A single-use round flexible mixing bag for use in bioprocessing in which a fluid is received and agitated using an internal fluid-agitating element comprising a radial flow impeller driven by an internal pneumatic vane motor is disclosed. The bag may include an integral sparger and sensor receiver. Related methods are also disclosed.

Abstract: Large-scale downstream processing of secreted recombinant proteins is provided in a single device, wherein the contents of a plurality of bioreactors are combined simultaneous to their harvesting and purification resulting in significant savings of time and the cost of manufacturing.

Abstract: An assembly capable of capturing and purifying expressed biological products during or at the end of a bioreaction cycle is disclosed wherein a binding resin is kept separated from the contents of the bioreactor allowing capturing, harvesting and purification of biological products in a bioreactor; the invention additionally provides means of removing undesirable metabolic products as well as provides for efficient loading of chromatography columns.
