The Lee VHS Injection Manifold Mount System allows for the precise injection of fluid into a flow stream. Using this system, any ported Lee VHS micro-dispense valve can be mounted so that the outlet port is in close proximity to the flow stream, thus minimizing captive capillary volume and increasing injected volume repeatability. Lee VHS valves are high-speed, two-way solenoid valves that have set the standard in applications requiring microliter and nanoliter dispense volumes.
