A pneumatic driver for a syringe is provided. The syringe has an elongated barrel with a cap secured to the proximal end that has a through bore. A filter is secured to the cap interior of the barrel that covers an opening in the through bore interior of the barrel. The pneumatic driver includes a source of pressurized air; a support for receiving and locating the syringe; and a supply block configured to receive pressurized air from the source and having an outlet for delivery of pressurized air. The supply block is movable between a first position spaced apart from the cap of the syringe and a second position in contact with the cap with fluid communication being established between the outlet of the supply block and the through-bore in the cap.
