Abstract: A cap for a syringe with Luer-lock connector comprising: a main body provided with a first handle portion and a second portion having an external threading for coupling with a corresponding internal threading of the Luer-lock connector of the syringe, an axial cavity having an aperture at the second coupling portion being formed in the main body; and a rubber housed in the axial cavity of the main body. The rubber has a surface facing the aperture of the axial cavity and designed to abut against an open free end of a tip of the syringe for air-tightly closing the open free end and raised elements are formed at the external threading of the second coupling portion.

Abstract: A dosing syringe including a hollow cylindrical body and a plunger sliding within the hollow cylindrical body. The hollow cylindrical body includes a main body and a proximal end provided with an aperture. The main body has at least one portion having a cross-section smaller than that of the proximal end, whereby a surface is delimited between the main body and the proximal end, which is configured to abut against a corresponding surface of an adapter, so that the proximal end is removable and liquid-tight blocked between said surface of the adapter and a bottom wall provided with an aperture of the adapter, the aperture of the proximal end and the aperture of the bottom wall being in direct fluid communication therebetween. An adapter for use with a dosing syringe as defined above and an administration kit including the dosing syringe and the relative adapter are also provided.

Abstract: A cap for a pre-filled syringe with a Luer-lock connector including a main body provided with a first handle portion and a second portion designed to be coupled to the Luer-lock connector, an axial cavity having an aperture at the second coupling portion formed in the main body; and a rubber housed within the axial cavity of said main body. The cap also includes a tapered portion, which is interposed between the first handle portion and the second coupling portion and is designed to air-tightly engage the Luer-lock connector, and the rubber has a surface facing the aperture of the axial cavity, the surface being designed to abut against an open free end of a tip of the pre-filled syringe for air-tightly closing the open free end.

Abstract: A dosing syringe including a hollow cylindrical body and a plunger slidable within the hollow cylindrical body. The dosing syringe includes at least one slider slidable within a distal flange of the hollow cylindrical body transversely to the hollow cylindrical body and at least one wall is formed in the plunger for abutting and blocking the slider during its sliding within the flange, wherein the at least one wall provides a mechanical stop which stops the stroke of the plunger at a predetermined volume of product to be aspirated and/or dispensed.
