A drug transfer device includes a vertically movable vial clamp for holding vials of various sizes in position with their septum facing downwards, a syringe holder and actuator that includes a clamp for grasping the plunger of the syringe and a movable tray for supporting a bag containing an infusion solution. The syringe holder is movable between an aspiration position below the vial clamp with the syringe or the needle attached thereto pointing towards the septum of the vial and an expelling positioning in which the syringe or the needle attached thereto is pointing towards an injection port of the infusion bag. When the vial and the syringe are in place with the syringe holder in the aspiration position the vial clamp moves downwards so that the needle on the syringe pierces the septum. The actuator withdraws the plunger to a predefined extent thereby aspirating the desired amount of drug. Then, the vial clamp moves up, thereby disengaging the needle. This event is followed by the syringe holder moving to the expelling position. Then, the tray moves towards the syringe holder until the needle penetrates the injection port. Next, the actuator depresses the plunger, and the drug is expelled into the bag whereafter the tray is moved away from the syringe to disengage the needle.
