A simple flow-through system for culturing or colonization purpose is described. It consists of piled up petri-dishes placed on top of a water reservoir with an air-water lifting tube. Each of the seperately removable units is composed of the bottom of a petri-dish glued on top of the lid of another one. A short piece of plastic tubing, fitting tightly into an exentrically drilled hole in the bottom part of the unit, permits a continuous flow of water through the whole column.
