Publication number: 20220161258Abstract: A bioprocessing filtration experiment system for filtering a liquid test medium as part of a filtration experiment in a filtration experiment section of the filtration experiment system, which filtration experiment section runs from a receptacle for holding the test medium to be filtered to a fluid outlet for the filtered test medium, wherein the filtration experiment system is designed to ascertain, as part of the filtration experiment, sensor data as experiment data for at least one filter, said experiment data being able to be taken as a basis for selecting and/or dimensioning the filter of a target system according to predetermined scaling criteria. It is proposed that the filtration experiment system can be preassembled on an at least partially programming-related and/or circuit-related, at least partially fluidics-related and/or at least partially sensor-related basis.Type: ApplicationFiled: November 23, 2021Publication date: May 26, 2022Inventors: Stefan Obermann, Dennis Groesche, Fabian Walter, Christian Lock, Hendrik Rosenberg, Martin Lohrberg, Roman Ritzka

Patent number: 8123397Abstract: A disposable container is provided for mixing media. The container has at least one closable opening for introducing and/or removing media and has sensor mounts at spaced apart locations on the wall of the container. Each sensor mount has a front surface facing into the container and a rear surface sealed against the wall of the container. Sensors are embedded in the respective sensor mounts at positions adjacent the front surfaces. The sensors measure at least one specified parameter of the media at spaced apart locations in the container. The seals between the rear surfaces of the sensor mounts and the wall of the container ensure sterility for the media in the container.Type: GrantFiled: December 21, 2006Date of Patent: February 28, 2012Assignee: Sartorius Stedim Biotech GmbHInventors: Reinhard Baumfalk, Oscar-Werner Reif, Stefan Obermann, Dieter Schmidt

Patent number: 8093015Abstract: The invention relates to a method for determining the viability of cells in cell cultures, said method comprising the steps of: coloring the sample with a dye which can penetrate into individual cells depending on the viability of the latter, determining the proportions of cells which are colored to differing extents. The invention is distinguished by virtue of the fact that a cell suspension of the colored cells is centrifuged as a sample in a sample vessel (10) until the solid content present in the sample has settled as a compressed cell cake (13), and, in order to determine the proportions, the volumes of differently colored sections (131, 132, 133) of the compressed cell cake (13) are determined as a measure of the proportions of cells of different viability.Type: GrantFiled: April 24, 2007Date of Patent: January 10, 2012Assignee: Sartorius Stedim Biotech GmbHInventors: Stefan Obermann, Reinhard Baumfalk, Oscar-Werner Reif, Florian Wurm, Maria de Jesus, Matthieu Stettler, Martin Jordan
