ABSTRACT OF THE INVENTION The invention provides apparatus for injecting a sample of a fluid into a sealed pouch. The apparatus includes a framework and an injection needle for coupling to a source of the fluid to supply the fluid to the pouch. A drive mechanism is attached to the framework and is coupled to the injection needle for operation to move the needle between a withdrawn position and an engagement position with the needle moving along a first line of travel. A hopper is attached to the framework for containing a plurality of pouches in a stack, and a transport mechanism is attached to the framework and has a shuttle moveable along a second line of travel at right angles to the first line of travel. The shuttle moves pouches one at a time from the hopper to a position in line with the needle to receive the sample from the needle with the needle in the engagement position. The mechanism also includes an ejection means coupled to the framework and operable to push the pouch off the shuttle to make room for another pouch from the hopper and a control means coupled to the drive mechanism, transport mechanism and ejection means to operate the parts of the apparatus in sequence.
