Abstract: A multi chamber syringe unit (1) comprises a body (2), a separating element (3) and a bypass arrangement (26). The body (2) has a distal end side (23), a proximal end side (22) opposite to the distal end side (23), an interior limited by a side wall (21) between the distal end side (23) and the proximal end side (22) and a longitudinal axis (27) centrally extending from the distal end side (23) to the proximal end side (22) through the body. The separating element (3) is arranged in the interior of the body (2) forming a distal chamber (24) between the distal end side (23) and the separating element (3) and a proximal chamber (25) between the proximal end side (22) and the separating element (3). The bypass arrangement (26; 260; 268; 269) is a section of the body (2) in which the interior has a constant noncircular cross section (261) orthogonal to the longitudinal axis (27).

Abstract: A method for providing a dried solid product containing an active pharmaceutical ingredient is disclosed and includes providing a primary packaging container, providing a drying cartridge different from the primary packaging container, the drying cartridge made of a material adapted to hold a liquid product to be dried, wherein the liquid product contains an active pharmaceutical ingredient and the drying cartridge is made of a material having a thermal conductivity higher than the thermal conductivity of glass. The method also includes filling the liquid product into the drying cartridge, drying the liquid product in the drying cartridge to form a dried solid product containing the active pharmaceutical ingredient, transferring the dried solid product into the primary packaging container.

Abstract: A method of preparing a double chamber container (1) comprises the steps of: filling a substance in the interior of the double chamber container (1), freeze-drying the substance inside the double chamber container(1), inserting a middle plunger (81) in the interior of the double chamber container (1) such that a distal chamber and a proximal chamber are formed, wherein the middle plunger (81) seals the distal chamber from the proximal chamber and wherein the freeze-dried substance is inside the distal chamber, filling a reconstitution medium in the proximal chamber of the double chamber container (1), and sealing a distal opening (14) of the double chamber container (1) and a proximal opening (13) of the double chamber container (1).

Abstract: A device (1) for closing a chamber of a container having an opening for accessing the chamber comprises a plunger, a plunger seat (11), a container carrier (13) and a spacer (12). The plunger seat (11) releasably holds the plunger in a predefined alignment. The container carrier (13) is arranged to be connected to the container in a predefined position and alignment in relation to the opening of the container. The spacer (12) is arranged to position and align the plunger seat (11) adjacent to and distant from the container carrier (13) such that the opening of the container is open when the container is connected to the container carrier (13).

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.
