1. A valve for mixing a mobile phase in a sample separation device for separating a fluidic sample, the valve comprising:
a fluid inlet for supplying the mobile phase to be mixed to a mixing volume;
a movable body configured to rotate and axially move in the mixing volume to thereby mix the mobile phase, wherein the movable body is disposed in the mixing volume without being attached to the valve; and
a fluid outlet for supplying the mixed mobile phase to a mobile phase consumer,
wherein the movable body is configured to selectively open or close a flow path of mobile phase through the fluid inlet, along the mixing volume and through the fluid outlet, and comprising at least one of the following features:
wherein the movable body is configured to selectively open or close the flow path by being actuated by an axial movement;
wherein the movable body is configured to be actuated by the mobile phase.
