Solenoid valve manifold for flow injection applications

An injection manifold mount system, which enables the precise injection of a fluid into a flow stream, is available from Lee Products' range of miniature components.

The system allows any ported Lee VHS (Very High Speed) micro-dispense solenoid valve to be mounted so that the outlet port is in close proximity to the flow stream. This ensures the dual benefit of minimal captive capillary volume and increased injected volume repeatability.

Lee VHS two-way solenoid valves are suitable for applications requiring very precise liquids control down to microlitre and nanolitre dispense volumes. The new mount system is suitable for laboratory, biomedical and chemistry applications but especially for flow injection analysers.
Key features include: captive capillary volume of 0.5 microlitre, pressures up to 120psi, Teflon (ferrule) is the only additional wetted material, so the mounting nut and pressure plate do not contact the fluid and the valves can be rotated after installation without compromising the seal.

The manifolds are available in one, two, three and four-place standard options. However, for greater flexibility, and to enable future expansion, boss plugs are available to effectively seal any unused valve ports in the manifold. Valves and plugs can be installed and removed repeatedly as required.
