Micro-dispense Nozzles for Optimum System Flexibility

May 14 2007

A new range of Micro-Dispense Nozzles which provide a convenient method of accurately controlling dispensed volumes of liquid in the microlitre to nanolitre range, are now available through miniature component specialists Lee Products.

Lee Micro-Dispense Nozzles are designed to be used in conjunction with Lee VHS (Very High Speed) Micro Dispense Solenoid Valves, a combination which provides users with a range of features and benefits. For example they are, extremely compact, removable, available in a wide range of restrictions and can also be supplied in custom sizes with mounting options also available.

They are available in two different mounting configurations to enable optimum system design flexibility, 062 MINSTAC® threaded ends and straight tube. Nozzles with 062 MINSTAC ends are designed to be threaded directly into Lee VHS valves equipped with 062 MINSTAC outlet bosses.

The threaded design is ideal for higher pressure and close-coupled systems and also provides a simple, reliable and leak-proof connection to Teflon® tubing, such as when system requirements dictate that the nozzle must be located further from the valve.

Threaded nozzles can be easily removed for cleaning or to change orifice sizes, should a different dispensing range be required.

The straight tube versions are designed to accommodate press-on tubing connection to Lee VHS valves with straight outlet ports. This connection can be made easily using any soft, flexible tubing that is compatible with the system fluid, for example PVC, EVA, FKM and EPDM.

In addition to the standard stainless steel dispensing nozzles, Lee Products also offer a limited number of Teflon® coated nozzles where the Teflon coating is provided to help prevent ?hanging' drops at the end of a dispense. The Teflon is intended as a hydrophobic coating and not intended as a corrosion resistant barrier.
