The ASCO’s patented Series 458 rocker isolation valves are designed for use with the neutral or highly aggressive liquids found in analytical instrumentation.
Hermetic separation of the control mechanism prevents particulate contamination caused by friction of moving parts, assuring maximum purity of liquid samples. A special rocker mechanism prevents heat transfer to the fluid, eliminates the sticking effect of the valve seat, and significantly reduces erratic liquid flow. Typical applications include in vitro diagnostics, DNA sequencing, hematology, and surgical fluid management.
