Patent number: 9138662Abstract: A chromatography column and method of maintenance is described which does not require the use of a hoist or crane for disassembly. The method provides improved operator safety by reducing the need for the operator to work below a suspended or supported load within the column. Furthermore, the removal or replacement of column components is facilitated by providing access to the interior of the column and by the provision of a handling device.Type: GrantFiled: February 18, 2013Date of Patent: September 22, 2015Assignee: GE Healthcare Bio-Sciences ABInventor: Stefan Kjell Eriksson
