ASCO 067 Series Rocker Valve

Brand: ASCO

The ASCO 067 Series is a line of rocker solenoid fluid isolation valves for use with neutral or aggressive liquids and gasses in analytical and medical systems. The valves excellent self-draining capability and easy-to-flush, low-volume internal cavity make it ideal for applications where cross-contamination must be minimized. A special rocker mechanism, combined with a separating diaphragm, prevents heat transfer to the fluid and eliminates the sticking effect of the valve seat. Typical application include pipette dispensing, in-vitro diagnostics, DNA sequencing, and surgical fluid management.
  • Hermetic separation of control mechanism prevents particulate contamination caused by friction of moving parts, assuring maximum liquid sample purity.
  • Hit and hold feature utilizes an integrated power-save switch that reduces analytical instrument power consumption.
  • Meets all relevant CE directives and is RoHS compliant for lead-free applications.
