ABSTRACT:
A precision reagent metering and delivery device including a threaded, disposable reagent container adapted to be threadably interconnected with a threaded base. The reagent container is provided with a fluid passageway leading to the exterior thereof. Sealably mounted within the reagent container is a plunger which is operably coupled with a stator disposed in the base so that rotation of the reagent container relative to the base will cause precisely predeterminable longitudinal movement of the plunger within the reagent container whereby the reagent within the container will be controllably forced out the fluid passageway in precisely determinable amounts.
