Abstract
Possible differences in the disinfection rate of two irradiation conce pts, e.g. irradiation in cuvettes and petri dishes, were examined and quantified on a UV laboratory irradiation plant unit. In addition the geometrical parameters of the irradiation vessels and mixing of the ba cterial suspension during UV irradiation were considered. The results showed differences in disinfection rates of more than 2 log between di fferent sample areas in the vessels. The mixing caused an improvement of the disinfection rates in unfavourable irradiation areas of the cuv ettes and in contrast a deterioration in all irradiation areas in the petri dishes.
