ABSTRACT:
A microbiological analysis cup having a flat bottom, a wall with a circular section connected to this flat bottom and an open end. Moving from the flat bottom wall of the cup, there are at least three superposed tapered zones whose respective base diameters increase from the flat bottom to the open end.
The cup makes it possible to work with very small volumes of bacterial suspension for short incubation periods, which makes it very economical to use.
