Abstract
In an automatic chemical analyzer, a reagent dispensing system is provided for delivering reagent from containers in a reagent compartment to reaction stations. A mounting block assembly is formed with a first bore therethrough for providing a reagent flow path whose direction of flow is regulated with check valves. A second bore normal to the first bore and communicating therewith is provided for receiving a piston having travel-limiting radial flange means formed at the end thereof remote from the first bore. A solenoid is mounted to the block having a plunger for activating the piston.
