Abstract
The distributor device for a column includes a system of distributor tubes and nozzles for a fluid. The outlet apertures of the nozzles are preferably all arranged at the same height. At least a portion of the nozzles are manufactured of similar glass tube pieces. Each outlet aperture has a border which is formed by an edge produced by a milling cut and is otherwise untreated or by an untreated, broken glass edge.
