Abstract:
1. A microbiological analysis method, comprising the steps of: selecting an analysis assembly comprising: a filtration unit and a gel growth medium cassette, said filtration unit comprising a filter membrane and a body with which said membrane is associated, said cassette comprising a body containing the said gel growth medium, the latter having a surface designed to be covered by said membrane, the body of the filtration unit and the body of the cassette are adapted to cooperate in order to occupy a nested position in which the membrane covers said surface of said gel growth medium, the body of said unit and the body of said cassette each being equipped with an intermediate stop, when said stops are in contact with one another, the filtration unit and the gel growth medium cassette are in an intermediate position in which said membrane is spaced away from said gel growth medium, said intermediate stop of said body of said cassette comprising a ring connected to said body of said cassette by frangible tabs; engaging said unit on said cassette until the intermediate stop of the body of said unit comes into contact with the intermediate stop of the body of said cassette; and breaking said frangible tabs causing said ring to move clear so as to allow said unit to move from said intermediate position into said nested position.
