Publication number: 20190154639Abstract: A method for packing a chromatography column with chromatography media, comprising the steps of: providing a system comprising a column tube (3,19,21) having a closed first end (5) comprising an inlet/outlet (7), a media inlet (15) adjacent a second end of the column tube and an adaptor (9) positioned inside the column tube initially adjacent the second end of the column tube for sliding and sealing contact with an inner face of the column tube, the column tube and adaptor arranged initially such that they define an internal volume and such that the media inlet is in fluid connection with the internal volume; connecting a media slurry source to the media inlet; at least partially filling the internal volume with media slurry via the media inlet; forcing the adaptor towards the first end of the column tube to reduce the internal volume such that the media inlet is no longer in fluid connection with the reduced internal volume.Type: ApplicationFiled: January 6, 2017Publication date: May 23, 2019Inventors: Klaus Gebauer, Dan Hermansson

Patent number: 7896310Abstract: A pinch valve is adapted to hold at least one flexible tube in a tube holding room (7) and comprises a plunger (13) adapted to protrude into the tube holding room and pinch the tube against an opposite side wall (11) thereof. The plunger (13) is controllable to be positioned in at least two different positions, an open position where the tube in the tube holding room (7) is not pinched, and a pinching position where the tube is pinched between the plunger (13) and the opposing wall (11). The pinch valve further comprises a tube retaining means (19) adapted to prevent the tube from escaping from the tube holding room (7), especially when the plunger (13) is in the open position, and which can be pivoted into at least two different positions, a non locking position used during insertion of a tube into the tube holding room (7), and a locking position for retaining a tube inside the tube holding room (7) even when the plunger is in an open position.Type: GrantFiled: December 10, 2007Date of Patent: March 1, 2011Assignee: GE Healthcare Bio-Sciences ABInventors: Bjorn A. Johansson, Roger Lundqvist, Dan Hermansson
