The present invention relates to a fluid distributing device for distributing fluid into a column and to a fluid collecting device for collecting fluid from a column. The invention relates also to methods of using the devices of the present invention. The distributing device and/or the collecting device of the present invention can be used in fixed or fluidized bed reactors or columns, such as chromatographic separation columns, ion exchange columns, adsorption columns etc. A fluid distributing device comprises a) a first fluid conveying system; and b) a distributing plate, which comprises i) first means for fluid transfer for dividing the fluid flow coming from the delivering points into several partial fluid flows and for distributing the partial fluid flows into the column; and ii) first means for controlling of the partial fluid flows by differential pressure in the first means for fluid transfer.

The fluid collecting device according to claim 1, wherein the second means (14) for controlling the partial fluid flows comprises a nozzle or an opening between fluid transfer port (12) and the collecting channel (13). 11. The fluid collecting device according to claim 1, wherein the fluid is collected from at least part of the length of the collecting channels (13; 13b). 12. The fluid collecting device according to claim 11, wherein the cross-section area of the collecting channel (13; 13b) increases from the beginning of the collecting channel towards the second means (14) for controlling the partial fluid flows. 13. The fluid collecting device according to claim 1, wherein the column comprises a column filling material. 14. The fluid collecting device according to claim 13, wherein the second fluid conveying system (11) and the collecting plate (9) are situated completely outside the column filling material. 15. The fluid collecting device according to claim 14, further comprising a screen for separating the collecting plate from the column filling material. 16. The fluid collecting device of claim 14, wherein the column filling material is chromatographic resin bed. 17. A method for collecting fluid from a column characterized in that a fluid collecting device according to claim 1 is used and the method comprises the steps of a) collecting the fluid evenly from the cross-section of the column to the collecting channels (13b); b) conveying the fluid from the collecting channels (13b) to the second fluid transfer ports (12) through the second means (14) for controlling the partial fluid flows by differential pressure; c) conveying the fluid from the second fluid transfer ports (12) into the collecting points (10); and d) conveying the fluid from the collecting points (10) into the second fluid conveying system (11).
