  • Patent number: 11952155
    Abstract: A method of manufacturing a flexible container housing a drug substance is disclosed that includes forming a first compartment from a flexible sheet-like material, filling a liquid into the first compartment, sealing the first compartment, forming a second compartment from the flexible sheet-like material, filling a dry drug formulation into the second compartment, and sealing the second compartment. The method further involves lyophilizing the drug formulation inside a tubular cartridge, filling the second compartment by introducing the tubular cartridge through an opening of the second compartment such that an open end of the tubular cartridge is positioned distant from the opening of the second compartment, providing the drug formulation from the open end of the tubular cartridge into the second compartment, and withdrawing the tubular cartridge from the second compartment. The first and second compartments are separated by a frangible seal which opens when the first compartment is compressed.

  • Publication number: 20230346641
    Abstract: A lyophilisate retainer for lyophilizing a substrate is disclosed that includes a three dimensional scaffold body having pores. The pores of the scaffold body are configured to receive and hold the substrate. The scaffold body is made of a scaffold material providing heat transfer properties in lyophilisation to induce heat transfer to the substrate held in the pores of the scaffold body.

  • 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).

  • Publication number: 20220221410
    Abstract: An inspection device (1) has a particle detector (3) adapted to detect particles (5) in a liquid, a seat (6) adapted to position a container (4) housing the liquid in an area of operation (311) of the particle detector (3) and a vibration arrangement (2) for vibrating the container (4). The vibration arrangement (2) comprises a frequency generator (21) adapted to provide an electrical signal and a transducer (22) adapted to transduce the electrical signal provided by the frequency generator (21) into an acoustic wave (221). The seat (6) is adapted to position the container (4) adjacent to the transducer (22). for inspecting a liquid inside a container (4) with respect to the existence of particles (5). The inspection device (1) allows for an accurate and gentle inspection of the liquid filled in the container and for detecting particles in the liquid.

  • Publication number: 20220023148
    Abstract: A lyophilisate container (39) comprising a compartment; a wall (3119, 3129) limiting the compartment; and a lyophilisate arranged inside the compartment. At least a portion of the wall (3119, 3129) is semipermeable allowing vapour permeation in one direction out of the compartment through the wall (3119, 3129) and preventing vapour permeation in an opposite direction into the compartment through the wall (3119, 3129).
