Abstract: A hollow conductor has a first flange, a second flange, a flexible hollow conductor section, and a first fastening unit. The flexible hollow conductor section is electrically connected both to the first flange and to the second flange in such a way that a radio-frequency signal (RF signal) can be transmitted from the first flange to the second flange or vice versa via the flexible hollow conductor section. The flexible hollow conductor section has a surface, and a first depression is arranged in the surface. The first fastening unit is connected to the first flange. The first fastening unit rests against the surface of the flexible hollow conductor section in a first overlap region in a longitudinal direction of the flexible hollow conductor section and engages in the first depression of the flexible hollow conductor section and thereby fixes the flexible hollow conductor section with respect to the first flange.

Abstract: Provided herein are methods and systems for use with peristaltic pumps. More particularly, provided herein are peristaltic pump systems that include a dampener for reducing the pulsations of the flowrate from the peristaltic pump system to produce, mix, transfer and/or manufacture pharmaceutical compositions and formulations, including pharmaceutical compositions and formulations comprising lipids and RNA.

Abstract: A circuit arrangement having two interconnected high-frequency components, namely a first component and a second component, is described. A connection for transferring high-frequency signals is arranged between the first component and the second component. The connection includes at least one inner conductor, which is at least partially enclosed by an outer conductor. The inner conductor is connected to the first component and to the second component in order to transfer high-frequency signals. The second component includes a contact surface on a connecting surface and the inner conductor is pressed using a pressure force onto the contact surface, to establish a high-frequency connection between the first component and the second component.
