    摘要： A valve block (1) for a dosing device, with an arrangement of piston pipettes (2) or other dosing means, comprises, on the one side thereof, a pattern of openings (15) which may be placed on the arrangement of piston pipettes (2) and, on the opposite side thereof, a second opening (16) corresponding to each first opening (15). The valve block (1) further comprises a number of channel systems (20), each with a main connector (23). The valve block essentially comprises a number of plates (10, 11, 12, 13), arranged in a stack. All plates have through holes (14), arranged in the pattern of the first holes (15). At least a part of the plates (11, 12, 13) additionally comprises a channel system (20) with channels (21), connected to the main connector (23), whereby said channels (21) form a pattern which matches the pattern of the through holes (14) and is laterally displaced relative thereto. In order to optionally connect the first openings (15) to the corresponding second opening (16) or to a selected channel system (20), said plates (11, 12, 13) with the channel system are optionally laterally displaced.

    摘要： A fluid control device comprising a pivotable member (8) which has a planar major face (22) and is mounted so as to enable pivotal motion about an axis (11) parallel to the major face. The pivotable member including a fluid jet channel (29) which directs a fluid jet towards a fluid receiving channel (37) defined in a receiving member (7). The pivotable member is pivotally rotated about the axis by means operable to pivot the pivotable member. This means may be an electromagnet (14) disposed with its poles (20,21) adjacent and parallel to the major face of the pivotable member. The motion of the pivotable member alters the relative positions of the fluid jet channel/channels and the fluid receiving channel/channels and thereby the quantity of fluid received by the fluid receiving channel/channels.
