  • Scalable inlet liquid distribution system for large scale chromatography columns
    Patent number: 7051758
    Abstract: A uniform fluid distribution system (2) for use with a liquid transfer system (100) for maintaining an interface between liquid phases within a large scale separator system including a cell of circular or rectilinear cross-section into which liquid may be introduced as discrete phases at an inlet zone occupying a first approximately transverse cross-sectional region of said cell and output at an outlet zone occupying a second approximately transverse cross-sectional region of said cell. Said distribution system (2) comprises at least one liquid inlet (24) and one distribution outlet (32), which are connected by an internal flow connection system (36).

  • Endpiece for a chromatography column
    Patent number: 6936166
    Abstract: A liquid transfer system (100) comprising a net (170) and a net support (160), wherein, the net (170) is integrally joined with the net support (160). The net (170) and the net support (160) are preferably joined by welding, such as contact welding or by welding at a lower edge (400) of a number of welding-holes (350) that extends through the net support (160).
