Patent number: 11898938Abstract: Integrity of a flexible bag already filled with a biopharmaceutical fluid is verified by a receiving and controlling device. The first wall and a second wall, forming two opposite walls on both sides of a longitudinal axis of the bag, are in contact with the fluid and with two parallel restraining plates of the device, while test pressure is controlled. Additionally, an integrity/non-integrity indicator device that comprises a pair of covering walls is provided to be interposed between the bag walls and the restraining plates. A leak through the bag walls can be detected by a color change of at least one continuous colorimetric detection layer, integral with or included in the pair of covering walls. Such continuous colorimetric detection layer is included in a permeable or impregnable layer.Type: GrantFiled: March 20, 2020Date of Patent: February 13, 2024Assignee: SARTORIUS STEDIM FMT SASInventors: Marc Hogreve, Martin Dahlberg

Publication number: 20170109104Abstract: The present invention relates to a printer being capable of parsing, understanding and evaluating multiple target package files that include printing resources not only for a single printer or for a single type of printer, but for multiple printers or multiple types of printers. For this purpose, the package file is augmented with platform information that is separately associated with each printer resource included in the package file. Thereby, the parser of the printer can discriminate whether or not a particular resource is applicable to itself. Consequently, only the resources such as firmware are installed that are valid and applicable to the printer. In the same manner, the resources can also be augmented with individual printer information, so as to indicate different resources to be installed on different printers, even if they are of the same type.Type: ApplicationFiled: March 28, 2014Publication date: April 20, 2017Applicant: SATO HOLDINGS KABUSHIKI KAISHAInventors: Martin DAHLBERG, Lars-Åke BERG, Magnus WIBECK, Per ANDERSSON, Mats HEDBERG

Patent number: 9534980Abstract: A method for testing the integrity of a bioreactor container includes providing a bioreactor container having a fluid-tight, at least locally flexible wall and having at least one container opening and providing a test apparatus having a bioreactor container compartment and a fluid-permeable and/or structured reception sheet arranged replaceably on the bioreactor container compartment. The method continues by arranging the bioreactor container in the bioreactor container compartment so that the bioreactor container wall contacts the reception sheet in the bioreactor container compartment, connecting the container opening of the bioreactor container to a fluid source filling the bioreactor container with a fluid from the fluid source to generate a predetermined positive pressure P1 in the bioreactor container at a first time T1 and determining whether the bioreactor container is sufficiently leaktight.Type: GrantFiled: June 26, 2012Date of Patent: January 3, 2017Assignee: SARTORIUS STEDIM BIOTECH GMBHInventors: Martin Dahlberg, Isabelle Gay, Lars Boettcher, Stefan Obermann, Rainer Sandrock

Patent number: 9459175Abstract: A method for testing a flexible container includes arranging the flexible container on a winding core that can be rotated about a winding axis W and forms an internal support. The method continues by winding the flexible container around the winding axis W arranging an external support around the wound container and connecting at least one container opening of the container to a fluid source. The method proceeds by filling the container with a fluid from the fluid source to generate a predetermined positive pressure P1 in the flexible container at a first time T1 and determining whether the container is sufficiently leaktight.Type: GrantFiled: May 15, 2012Date of Patent: October 4, 2016Assignee: SARTORIUS STEDIM BIOTECH GMBHInventors: Martin Dahlberg, Lars Boettcher, Thomas Regen, Stefan Obermann, Marc Hogreve
