Abstract: The application relates to a cartridge for a plurality of petri-dishes, comprising a cylindrical cartridge housing configured to receive the plurality of petri-dishes in a stack aligned with an axial direction of the cartridge housing in an interior space of the cartridge housing such that the stack of petri-dishes can be moved in the axial direction within the interior space. An axial end portion of the cartridge housing has a first opening dimensioned so that the petri-dishes can be exposed from the cartridge housing by sliding in the axial direction. Another axial end portion of the cartridge housing has a second opening dimensioned to prevent removal of the petri-dishes through the second opening and so that a piston can be inserted into the interior space of the cartridge housing for moving the stack of petri-dishes (P) in the axial direction towards the first opening.

Abstract: The present application relates to a transfer device (60) for transferring a plurality of objects (O) through a transfer port (R), comprising a container (61) with an internal space (67) configured to accommodate the plurality of objects (O) to be transferred through the transfer port (R). The container (61) has at least one extraction opening (62) at an end portion of the container (61) in an axial direction (X) dimensioned such that the objects (O) can be removed from the container (61) at least individually, a door (63) configured to selectively close the at least one extraction opening (62) and seal the internal space (67) from the environment, and a piston (64) arranged in the container (61) so as to be movable in a translational motion in the axial direction (X) towards/away from the at least one extraction opening (62) to move the objects (O) accommodated in the container (61).

Abstract: The invention concerns a filtration assembly for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a lid device (40) removably and fluid tightly attachable to the other axial opening of the reservoir (20) to close the opening. Further, the lid device (40) is removably and fluid tightly attachable to the membrane support (10) so as to seal the one axial side of the membrane support (10) from the environment.

Abstract: A support apparatus for a filter membrane comprises a base support and a disc-shaped porous support member. The member is removably received in a seat portion of the base support in fluid communication with a drain. A bottom side of the disc-shaped porous support member is supported in a support plane. The bottom side of the member is unsupported in an area and the unsupported area is adjacent to a space in the seat portion of the base support that is located and dimensioned such that application of a force, onto the top side of the member at a location substantially within the boundaries of the unsupported area at the bottom side will cause the member to pivot/tilt into the space and lift above the support plane at a diagonally opposite side from the location where the force is applied so that it can be easily grasped and removed.
