Patent number: 11794154Abstract: A mixing apparatus (1) for mixing a fluid and/or solid. The mixing apparatus includes a mixing container (100) having an interior in which the fluid and/or solid can be arranged. A feed-through passage (10) extends through a container wall (101) of the mixing container. A drive shaft (50) is fed through the feed-through passage, to drive a stirring element (30) arranged at least partly in the interior of the mixing container. The stirring element is used to mix the fluid and/or solid arranged in the mixing container. A drive-side shaft end (51) of the drive shaft couples the drive shaft to a drive (120) arranged outside of the mixing container. An adjustable seal (70) seals off the feed-through passage. A setting apparatus (80) is provided to switch the adjustable seal into at least two sealing operation states having different sealing effects.Type: GrantFiled: February 10, 2020Date of Patent: October 24, 2023Assignee: SARTORIUS STEDIM BIOTECH GMBHInventors: Stefan Zeuch, Markus Haeusser, Stefan Weisshaar, Jens Ludwig

Patent number: 9044718Abstract: A mixing vessel includes a flexible container, elements for mixing its contents, aeration elements, a drain/lower bearing port having a rigid flange provided with a drain passage, attached in a tight manner to the lower portion of the container wall, supporting a lower bearing that is adjacent to the drain passage. The vessel includes an extended element for dispensing aeration gas and is spaced essentially radially from the drain/bearing port; at least one tubular element for dispensing aeration gas extends from the extended dispensing element, in the inside space, along the inside surface of the lower portion and the side portion of the wall of the container and extends on the outside of the container from the upper portion; at least one mixing element is spaced essentially from the lower portion of the container wall, from the lower bearing, and from at least one extended element for dispensing aeration gas.Type: GrantFiled: March 18, 2009Date of Patent: June 2, 2015Assignee: SARTORIUS STEDIM BIOTECH GMBHInventors: Jens Ludwig, Oscar-Werner Reif, Gerhard Greller, Wolfgang Kahlert, Günter Pradel, Michael Bates, Magali Barbaroux, Stephanie Baud, Isabelle Gay, Sebastien Chaussin

Patent number: 8268059Abstract: The invention relates to a waste gas system for bioreactors having a hydrophobic sterile filter, arranged at the end, and a heat exchanger which protects the sterile filter against blocking by liquid media. The gas outflow duct for discharging waste gas from a bioreactor vessel is divided in a cooling zone of the heat exchanger into a multiplicity of subducts and is extended in a heating zone of the heat exchanger to a calming zone. Due to the multiplicity of subducts, a considerably larger surface area for the removal of heat from the waste gas is available, with the result that in the case of laminar flow of the waste gas through the subducts a high effectiveness of the separation of liquids from the waste gas can be achieved.Type: GrantFiled: December 15, 2009Date of Patent: September 18, 2012Assignee: Sartorius Stedim Biotech GmbHInventors: Juergen van den Boogard, Gerid Hellwig, Jens Ludwig, Oscar-Werner Reif, Stefan Weisshaar
