VHS solenoid valve manifold ideal for flow injection tasks

VHS solenoid valve manifold ideal for flow injection tasks

An Injection Manifold Mount System which enables the precise injection of a fluid into a flow stream is the latest addition to the Lee Products range of miniature components. This new system means any ported Lee VHS (Very High Speed) micro-dispense solenoid valve can 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 acknowledged as having set the standard for applications requiring very precise liquids control down to microlitre and nanolitre dispense volumes. As a result, this new mount system will be ideally suited to laboratory, biomedical and chemistry applications but especially for flow injection analysers (FIA). 

Among the key features are, captive capillary volume of 0.5 micro litre, pressures up to 120 psi, a 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.
