Abstract

<PICT:0584841/III/1> A syringe device for delivering measured quantities of liquids is characterized by the provision of coacting stops integral with the barrel and piston. Thus, the piston rod stop comprises a bend 4, and the barrel stops the end 6 and a step 5. The contacting surfaces of the stops are preferably ground flat, and in the all glass construction shown, a delivery jet 7 is provided. Alternatively, a conical tip to accommodate a hypodermic needle may be provided. In modifications, a single stop may be provided on the barrel and two on the piston rod, or where volumes of different values are required, three or more stops on the barrel, and one on the piston or vice versa, or even a plurality on both rod and barrel.
