IMPROVEMENTS IN OR RELATING TO REACTION VESSELS

摘要

The present invention relates to a liquid distribution or collection device (100) for a vessel containing material to which the liquid is to be delivered, the device having a plurality of conduits (102, 103, 104, 105, 106) extending from a liquid transport channel (101), in which at least one said conduit comprises a proximal end (112) in communication with the liquid transport channel (101), a distal end (113) remote from the liquid transport channel (101) and, between said proximal and distal ends, a multiplicity of spaced apertures (118) for passage of liquid, wherein a distal region of the conduit has a cross-sectional area d₂ that is smaller than the cross- sectional area d₁ in a proximal region of the conduit. The present invention also relates to an ion exchange or filtration vessel (1) comprising said device and a method of distributing a fluid onto a substrate in a vessel using said device.
