  • Publication number: 20250383298
    Abstract: An inspection system (1.3) is operative to inspect a medical container containing a liquid. The inspection system (1.3) comprises an actuator (1.6) operative to displace a light source and/or detector of an optical system (1.5) relative to a sample holder (1.4) during data acquisition. Acquired data are analyzed to detect and/or determine characteristics of a particle in the medical container.

  • Publication number: 20240002773
    Abstract: A plate cleaning device (1) for cleaning a clamp plate of a fermenter, wherein the clamp plate has a plurality of receptacles each configured to hold a bioreactor vessel, and at least one conduit with a conduit opening per receptacle. The device comprises a plate seat member (3), a cover member (2), a plurality of valve units (4), a first fluid terminal (71), a second fluid terminal (74) and a control unit (9). The plate seat member (3) is configured to hold the clamp plate (6) in a predefined position and orientation. The cover member (2) is configured to close the plate seat member (3) such that the clamp plate (6) is tightly enclosed by the plate seat member (3) and the cover member (2). The plurality of valve units (4) is configured to be coupled to the cover member (2) such that at least one valve unit (4) is associated to each of the conduit openings (62) of the clamp plate (6).

  • Publication number: 20220390476
    Abstract: A fluid analysis arrangement (1) comprises a particle quantifying device (4), a holder (6), a robot (3), a washing station (5) and a control unit (2). The particle quantifying device (4) has a sensor unit (42) with a sensing stick (421) to be arranged in a fluid to sense for particles in the fluid, and an evaluation unit (41). The holder (6) has a plurality of seats each configured to receive a container in which a sample fluid is arranged. The control unit (2) is connected to the particle quantifying device (4) and the robot (3). The sensor unit (42) is mounted to the robot (3).

  • Patent number: 10209211
    Abstract: A method for determining whether reconstitution of a solution in a container is completed comprises the steps of: selecting a predetermined amount of a solid substance and a predetermined amount of a liquid solvent from which the reconstituted solution is to be prepared, preparing a solution by solving the predetermined amount of the solid substance in the predetermined amount of the liquid solvent, measuring the impedance (Z) or the resistance (R) of the solution, determining whether the change of the measured impedance (Z) or the resistance (R) within a measuring time interval of a predetermined duration is below a defined threshold, and determining that reconstitution of the solution is completed when the change of the measured impedance (Z) is below the defined threshold.

  • Patent number: 9446408
    Abstract: A system for dispensing a sample into a buffer liquid includes a pressure chamber having pressure supply means for generating an overpressure within the pressure chamber. An inlet capillary supplies a buffer liquid to an outlet end arranged in the pressure chamber, and an outlet capillary discharges the buffer liquid from the pressure chamber. The outlet capillary has an inlet end in the pressure chamber facing the outlet end of the inlet capillary to form a capillary gap. A dispenser having a dispensing end is in the pressure chamber at the capillary gap to allow the sample at the dispensing end to be dispensed into the buffer liquid entering the outlet capillary inlet end. The pressure chamber includes a sample port that allows the dispenser to be moved into and out of the pressure chamber.

  • Publication number: 20150238966
    Abstract: A system for dispensing a sample (5) into a buffer liquid comprises a pressure chamber (1) having pressure supply means for generating an overpressure within the pressure chamber. An inlet capillary (2) is provided for supplying a buffer liquid (9) to an outlet end (6) arranged in the pressure chamber. Also, an outlet capillary (3) is provided for discharging buffer liquid and/or sample from the pressure chamber. The outlet capillary (3) has an inlet end (7) arranged in the pressure chamber (1) facing the outlet end (6) of the inlet capillary (2) to form a capillary gap (8). A dispenser (4) having a dispensing end (10) is arranged in the pressure chamber (1) at the capillary gap (8) to allow the sample (5) at the dispensing end (10) to be dispensed from the dispensing end (10) into the buffer liquid entering the inlet end (7) of the outlet capillary (3).
