Abstract: The present application relates to a transport packaging (20) for a plurality of petri-dishes (P), comprising a shell-like main body (21) with a compartment (22) for holding the plurality of petri-dishes (P) in a parallel orientation, the compartment (22) being accessible from an opening (23) at one side of the main body (21), and a rack-like structure (24) formed in the compartment (22) for supporting the petri-dishes (P) in a fixed position during handling and configured to allow insertion/extraction of the petri-dishes (P) into/from the rack-like structure (24) in a direction.

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: The invention concerns a frame (1) for holding a plurality of filtration assemblies (100) and a testing unit (10) for microbiological testing. The frame (1) for holding the plurality of filtration assemblies (100) comprises an array of supports (5) each configured to receive and support one of the filtration assemblies (100) on a common support plane (2), and connection means (6) provided on the periphery (7) of the frame (1) and configured to releasably connect, by a form-locking engagement, a further frame (1) such that the common support planes (2) of the connected frames (1) are contiguous. Further, the testing unit (10) comprises at least one frame (1) packed in a bag (20) in pre-sterilized condition.

Abstract: A vacuum filtration head (1) having a receptacle for a support (2) for a membrane filter (3) for microbiological testing of a liquid substance to be drawn from an upstream side of the membrane filter (3) to a downstream side of the membrane filter (3) through the membrane filter (3), or the support (2) for such membrane filter (1), a drain chamber (4) located downstream of the support (2) and communicating with a downstream side of the membrane filter (3) receiving the liquid substance passed through the membrane filter (3), and a drain channel (5) communicating with the drain chamber (4) at an opening (9) and communicating with a vacuum. A protective shield (6) is arranged in the filtration head (1) interfering with a fictive direct line connection while retaining a fluid path (7) to the drain channel (5) past the protective shield (6).

Abstract: A filter device (1) for filtering complex fluid samples including a first filter funnel (2) having an inlet (2a), an outlet (2b) and a first internal space (2c), and a second filter funnel (3) having an inlet (3a), an outlet (3b) and a second internal space (3c). The first and second filter funnels (2,3) are sequentially arranged with a first filter medium (4) located therebetween such that a volume of sample fluid placed in the first internal space (2c) can pass through the first filter medium (4) and be collected in the second internal space (3c). An intermediate connector (12) is provided between the first filter medium (4) and the internal space (3c). The intermediate connector (12) has a port (13) and/or a vent for communicating the internal second space (3c) with an external gas source/atmosphere and/or a vacuum source via a valve arrangement (14).
