ABSTRACT:
A dispenser for blood and other biological specimens is disclosed which provides a means of obtaining a small predetermined quantity of specimen from a closed container without the need to remove the stopper from the container. The cannula of the device is caused to pierce the container's rubber stopper forming an assembly. When the said assembly is forced against a target surface, such as microscope slide, the force compresses the stopper and thereby reduces the volume inside the container sufficiently to eject a drop of fluid which is dispensed onto a target surface. Stabilizing supports are provided so that fluid emerges from a dispensing tip located a predetermined distance above the target surface which determines the quantity of fluid dispensed. The supports also transmit reactive force from the target surface to compress the rubber stopper of the closed specimen tube.
