Abstract:
1. Microbiological 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 cooperating in order to occupy a nested position in which the membrane is in contact with 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 with, when said stops are in contact with one another, the filtration unit and the gel growth medium cassette being in an intermediate position in which said membrane is spaced away from said gel growth medium, so as to allow said filtration unit to move from said intermediate position into said nested position, wherein the body of the unit and the body of the cassette are also each equipped with an end-of-travel stop, said end-of-travel stops being in contact with one another in said nested position.
