Abstract
A device for filling a pharmaceutical fluid into vials has a product container, which is connected to a distributor by way of a first line. Filling lines branch from the distributor and have filling valves for the individual vials. In order to improve the filling precision, particularly with fluids that have a very temperature-dependent flow behavior, the invention discloses cooling the distributor via a coolant so that during the filling procedures, the fluid has a substantially constant temperature. That substantially constant temperature then forms the basis underlying the calculation of the triggering time of the filling valves by a control unit with greater precision than is shown in the prior art.
