  • Publication number: 20240001260
    Abstract: The present invention relates to an apparatus (200) for bio-product processing. The apparatus (200) comprise a processing column (201) comprising an upper column tube (202B) releasably coupled to a lower column tube (202A). The lower column tube (202A) has a processing chamber (218) provided therein. The apparatus (200) additionally comprises an adapter (222) for moving within the processing column (201) so as to vary the volume of the processing chamber (218) within the lower column tube (202A), and a column stand (214) for supporting the adapter (222).

  • Patent number: 8632679
    Abstract: 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.
