ABSTRACT:
The present invention is directed to a system for locating a vial in a predetermined location with respect to a needle which is used to penetrate a septum in the vial. The system includes a vial carrier having a well for receiving a vial. A penetrable septum is disposed in an opening in the vial. At least one needle penetrates the septum at periodic intervals. Locating means are provided within the vial carrier for establishing a predetermined location of the vial in relation to the needle. The locating means includes a plurality of contact points and urging means for establishing contact between the contact points and the locating surface. The urging means presses substantially on one side of the vial, which side is substantially opposite the locating means.
