Abstract
A fluid dispensing and metering unit is described for dispensing fluids into a system without the introduction of microcontaminants into the fluid flow. This unit includes a block with a fluid conducting duct axially extending from the block's proximal face to the block's distal face. In communication with the fluid conducting duct is a combined dispensing and modulating means for regulating the amount of fluid entering the fluid conducting duct. A plurality of these units can be assembled to construct a flow control manifold, creating a single continuous duct for carrying all dispensed fluids.
