The invention relates to a dosing device for liquids, with a replaceable distributor rail () and a plurality of dosing units () that are hydraulically connected to the distributor rail (), wherein each dosing unit () has a valve unit (), preferably provided with a suction valve, a discharge valve and a discharge cannula (), and, detachably arranged on the valve unit (), a piston-cylinder unit () for drawing in and measured discharging of the liquid, wherein each valve unit () has a hydraulic connection element for detachable hydraulic connection to the distributor rail (), wherein the distributor rail () has an elongate fluid supply line, which has at its end side a supply connection () for the liquid and has dosing unit connections which are detachably coupled to the hydraulic connection elements of the dosing units ().

Dosing device for liquids

A dosing device with which several, preferably two, liquids can be measured and dispensed in precise quantities. In this dosing device, two bottle-top dispensers with integrated suction valves, discharge valves and a bottle-top mechanism are attached in a housing. A liquid-reservoir bottle can be affixed to the bottle-top mechanism of each bottle-top dispenser. In particular, affixing of the respectively associated reservoir bottles is ensured without confusion. Activation of the pistons of the bottle-top dispensers takes place with working strokes which differ depending on the spacing. In addition, the housing comprises a blow-out device by means of which, after each dispensing procedure, the discharge device for the liquids can be blown out and cleared of any liquid residues.

A dosing device is provided and comprises a withdrawal container and a dosing means comprising at least one dosing unit which is a piston-cylinder unit designed as a disposable member. The piston-cylinder unit discharges into a receiving container and valve means is provided to control flow into and out of the piston-cylinder unit.
