ABSTRACT:
A syringe for metering fluid in which a plunger contains a plurality of stop surfaces which contact a stop on a syringe tube. The stop surfaces are linearly displaced from each other along a longitudinal axis of the plunger by distances corresponding to predetermined volumes of fluid to be metered. The stop surfaces are also angularly displaced about the longitudinal axis of the plunger so that incremental rotation of the plunger permits successive stop surfaces to limit plunger motion, thereby effecting a precise metering of the fluid.
