Abstract
The invention relates to a nutrient medium unit for holding a filter of a filtration device, comprising a lower part that is filled with the nutrient medium and a lid, the latter having a fixing edge that protrudes into the lower part and that can be connected to an edge of the filter by means of an adhesive bond in order to remove said filter from the filtration device. The invention also relates to a method for the microbiological analysis of liquid samples, according to which a membrane filter is lifted off a filter support and laid on the surface of a nutrient medium that is situated in a lower part of a nutrient medium unit. The lower part is then covered by a lid, the latter being placed on the membrane filter lying on the filter support in such a way that a fixing edge located in the lid is connected to an edge of the filter by means of an adhesive bond. The lid and the attached filter are lifted off the filter support and placed on the dish-shaped lower part of the nutrient medium unit.
