The invention relates to a fluid distributor (9,10)for a column (1)comprising at least one cell (2) containing a bed of particles (3), the fluid distributor (9, 10) comprising: - a floor (11, 21) comprising at least one injection point (15, 25) providing a fluidic connection on either side thereof; - a layer of resistive medium (12, 22) fixed on one face of the floor(11, 21), the resistive medium being permeable to the fluid; - a spacing device (13, 23) inserted between the floor (11, 21) and the layer of reistive medium (12, 22) and maintaining a space for the circulation of the fluid between the floor (11, 21) and the layer of resistive medium (12, 22). The invention also relates to a column, in particular a chromatography column, provided with this fluid distributor.
