Solenoid Valves

VHS® Series 2-Way Dispense Solenoid Valve

This 6 mm dispensing valve combines inkjet printing technology with inert materials to achieve precision droplets in the nanoliter to milliliter range. With an ultra-fast response time (as fast as 250 µs), it is ideal for accurate fluid regulation and dispensing repeatable droplets with minimal satellites. The valve’s small size enables mounting in tight spaces, even in arrays directly above a well plate. It is offered with integrated precision orifices, nozzles, screens, or with our MINSTAC® connectors to vary the outlet nozzle and connect tubing. Each valve is customizable and 100% tested to ensure performance.

Key Product Facts
  • Dispense Volumes:As Low as 10 nL
  • High Speed:250 µs response time and up to 1 kHz operation
  • Low Internal Volume:As low as 30 µL
  • Long Cycle Life:250 M cycles min
  • Operating Pressure:Up to 120 psig

*Some models are rated for 0 - 30 psig only. Reference part number table.
**Typical cycle life on water; actual cycle life will vary depending on application conditions.
***Valve is sensitive to particles that are hard and fibrous. Larger, flexible particles, such as cells, can be qualified for applications.
****Dispensing frequency is based on water flow within the rated pressure range. Response time and dispense volume profile are drive dependent and vary depending on system parameters.
*****A spike and hold drive is required for most applications. To ensure solenoid coil temperatures remain within specification, duty cycle limitations may be required. Contact The Lee Company for recommendations specific to your application.
