Abstract: A mixing apparatus (1) for mixing a fluid and/or solid. The mixing apparatus includes a mixing container (100) having an interior in which the fluid and/or solid can be arranged. A feed-through passage (10) extends through a container wall (101) of the mixing container. A drive shaft (50) is fed through the feed-through passage, to drive a stirring element (30) arranged at least partly in the interior of the mixing container. The stirring element is used to mix the fluid and/or solid arranged in the mixing container. A drive-side shaft end (51) of the drive shaft couples the drive shaft to a drive (120) arranged outside of the mixing container. An adjustable seal (70) seals off the feed-through passage. A setting apparatus (80) is provided to switch the adjustable seal into at least two sealing operation states having different sealing effects.

The holders are in turn adapted to be releasably attached directly or indirectly to the base rack. The device arrangement further includes a positioning system which defines specific positions for the holders relative to the base rack.

Abstract: A modular processing system (100) for biopharmaceutical processes includes (i) at least one first and at least one second processing unit (30, 32), which can be fluidically connected to each other; and (ii) at least one adapter plate (200), through which at least one fluid flow (14), flowing from the first processing unit (30) to the second processing unit (32), can flow. The adapter plate deflects the fluid flow between the first processing unit and the second processing unit at least partially; and/or controls the fluid flow, preferably, the pressure thereof, in an open loop or closed loop manner. A method for the modular construction of a processing system (100) for biopharmaceutical processes is also disclosed.

Arranged in the retentate section (18) and/or in the permeate section (20) is at least one flow fitting (28) which is not formed from a woven or non-woven fabric, but from a structured plastic part, silicone part, metal part or ceramic part.

Abstract: A mixing apparatus (1) for mixing a fluid and/or solid. The mixing apparatus includes a mixing container (100), in the interior of which the fluid and/or solid can be arranged, and a feed-through (10) through a container wall (101) of the mixing container (100). A drive shaft (50), fed through the feed-through (10), is used to drive a stirring element (30), which is arranged at least partly in the interior of the mixing container (100), in order to mix the fluid and/or solid, arranged in the mixing container (100). A drive-side shaft end (51) of the drive shaft (50) is used to couple a drive (120), arranged outside of the mixing container (100), to the drive shaft (50). An adjustable seal (70) seals off the feed-through (10), wherein the adjustable seal (70) can be put into at least two sealing operation states having different sealing effects.

Abstract: A connecting system (1) has at least one connector (2) for a filter cassette (4) that can be inserted into a filter holder and has filter layers (5) between two end plates (6), and seals (7) between the filter layers (5) and/or between the end plates (6) and an adjacent filter layer (5). The connector has tensioning parts that engage in one another in a longitudinally displaceable manner and that can be fixed to the end plates (6) via their ends facing away from one another. The connector exerts a pretensioning force onto the end plates (6) when it is deflected to its maximum extent. The pretensioning force pulls the end plates (6) towards the filter layers (5), and when a contact-pressure force superimposed on the pretensioning force is applied to the end plates (6), the tensioning parts can be pushed towards one another correspondingly with the end plates (6).

Abstract: Aeration device for bioreactors with an aeration element with gas outlet openings arranged in a housing, the aeration element taking the form of a microsparger, the gas outlet openings of which are in each case spaced apart from one another and have a size of between 100 ?m and 200 ?m. At least one second aeration element with gas outlet openings of a second size is preferably provided, the aeration elements being formed by a common housing with separate aeration channels.

Abstract: One aspect of the invention relates to a filter module comprising: —a filter element having at least one filter medium which separates a filtrate side and a retentate side of the filter element from one another, and having a filter medium holder to which the filter medium is attached and which has at least one holder intake channel and at least one holder discharge channel, —a first filter cartridge part having at least one first cartridge intake channel and at least one first cartridge discharge channel, —a second filter cartridge channel having at least one second cartridge intake channel and at least one second cartridge discharge channel, wherein the filter medium holder is arranged in an arrangement position between the first filter cartridge part and the second filter cartridge part in a fluid-tight manner, wherein the at least one holder intake channel has a fluid connection with the at least one first cartridge intake channel and the at least one second cartridge intake channel, in order to form a mod

Abstract: A sensor device has an optical sensor (1), a container (2) and a compartmentalizer (3) that temporarily divides the container into a main space (4) and an adjacent space (5), in which the optical sensor (1) is located. The gas volume in the direct vicinity of the optical sensor (1) is reduced, as are also, consequently, the reactive products generated by radiation sterilization. The adjacent space (5) can be united with the main space (4) after the sterilization as a result of the temporary compartmentalization. The optical sensor is suitable for implementation in containers and laboratory products, such as, for example, disposable bioreactors, that are sterilized by gamma radiation.

Abstract: A sensor protector is intended to reduce the sensitivity of the optical sensor (4) to radiation products which, for example, are formed during sterilization with gamma radiation and to ensure simple and cost-effective manufacture. The sensor protector includes an upper part (1), a lower part (3) and an optical sensor (4). The optical sensor (4) situated on the lower part is positionable in an offset manner with respect to an opening (2) situated in the upper part and movable by means of displacement toward the opening (2) of the upper part (1). The sensor protector is suitable for use in containers and laboratory products that are sterilized by gamma radiation, for example disposable bioreactors.
