An injection manifold mount system that 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 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 liquid control, down to microlitre and nanolitre dispense volumes.
As a result, Lee said that this mount system will be ideally suited to laboratory, biomedical and chemistry applications, but especially to flow injection analysers (FIA).
Among the key features are: captive capillary volume of 0.5uL; pressures up to 120psi; and only one (Teflon) 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.
For greater flexibility and to enable future expansion, boss plugs are available to seal any unused valve ports in the manifold.
Valves and plugs can be installed and removed repeatedly as required.
