  • Patent number: 12000808
    Abstract: A fluid supply device for providing a mobile phase for a sample separating device includes, a supply conduit for providing a fluid which forms at least a part of the mobile phase, a fluid valve which is fluidically coupled with the supply conduit and, depending on its switching state, enables or prevents a passing of the fluid from the supply conduit, an elastic buffer unit which is fluidically coupled upstream of the fluid valve with the supply conduit and which is configured for buffering the fluid, and a fluid conveying unit for conveying the fluid which passes the fluid valve.

  • Patent number: 9291605
    Abstract: A valve for use in high-performance liquid chromatography has a spherical seat and a ball that, when it abuts against the seat, constrains a fluid from flowing through the valve and is capable of moving axially in order to allow the fluid to flow through the valve. The spherical seat has beveled outer faces in order that a force acting on the valve along the axial direction will generate a force acting on the ball. The inclination of the beveled outer face is such that a force acting on the ball counteracts a force exerted on the spherical seat by the ball and essentially compensates it.

  • Patent number: 9134335
    Abstract: A needle for handling a fluid in an analysis system is described. The needle includes a needle body made of a ceramic material and having a fluid conduit extending between a fitting end and a seat end. The fitting end is configured to be connected to a fitting and the seat end (308) being insertable into a seat. The needle body is tapering towards the fitting end. A fixing body is arranged on the needle body next to the fitting end for exerting an axial force when the needle body is connected to the fitting, and a slide-on element to be slid over the needle body so as to push the fixing body towards the fitting end.
