A flow control device, a system and a method are disclosed. The flow control device comprises a displaceable means () having a direction of displacement and being displaceable between a first position and a second position. The flow control device further comprises a body () comprising a first cavity () in fluid contact with a first side of the displaceable means () forming a first volume. The first cavity further comprising a first inlet (), a primary outlet () with a primary flow resistance and arranged essentially parallel with the displacement direction, wherein the primary outlet comprises an inlet opening () facing the displaceable means at a first distance () from the displaceable means in the direction of displacement, a secondary outlet () with a secondary flow resistance, wherein the displaceable means is displaceable between a first position and a second position. In the first position, a first fluid path () between the first inlet () and the primary outlet () is provided, and a second flow path () between the inlet () and the secondary outlet () is provided; In the second position, the displaceable means is displaced at least the first distance and close the inlet opening () of the primary outlet, whereby the inlet opening () is blocked, and the second fluid path () between the first inlet () and the secondary outlet () is maintained.

Method and device for flow control

The present invention relates to evaporation apparatus () comprising manifolds provided with at least one nozzle (), a tank unit () for a liquid, and a sample holder configured to be inserted into the tank unit. The sample holder is configured to hold at least one sample in a defined position relative the at least one nozzle a control unit () an inlet port () configured to be connected to a gas supply, a pressure regulator () arranged downstream the inlet port (). A set value of the pressure regulator () is controlled by the control unit (), a control valve () arranged downstream the pressure regulator (), wherein each of the at least one manifold (-) is connected to a corresponding output port of the control valve. The control valve is controlled by the control unit (), and the control unit is configured to set the set value of the pressure regulator to a value that causes a predetermined gas flow from each of the at least one nozzle.
