Abstract
An assembly comprising a flanged flask and a syringe device fixable thereto is provided. The syringe device includes a guide member for cooperating with the body of the flask. The guide member includes a first end with an internal guide surface at its terminal portion and a fastening mechanism set back from the internal guide surface. The internal guide surface cooperates with the cylindrical body of the flask and the fastening mechanism attached to the flange of the flask. A second end of the guide member provides translational guidance to a syringe.
