Abstract

The barrel is held in a bracket which is movable along the axis of the syringe between first and second position by a pair of actuators, the plunger actuator is mounted on the bracket, and the actuators are selectively energised by digital control loops to rinse the syringe with liquid from a sample container, to withdraw a repeatable and accurately measured volume of liquid from the sample container and to transfer liquid from the syrine to an injection port. The bracket and plunger are reciprocated alternately a number of times to repeatedly puncture an elastomeri cover on the sample container and to transfer liquid out of the container, and the plunger is actuated a pre-set number of times while the needle is immersed in the liquid. The actuators may be pneumatic. A number of sample containers may be positioned under the syrine in turn.
