The ASCO Series 385 rocker isolation valves are designed for use with the neutral or highly aggressive liquids used in analytical instrumentation.
The special rocker mechanism, combined with a separating diaphragm, prevents heat transfer to the fluid and eliminates sticking of the valve seat. Hermetic separation of the control mechanism prevents particulate contamination caused by the friction of moving parts, assuring maximum purity of liquid samples. Typical applications include in vitro diagnostics, hematology, DNA sequencing, and surgical fluid management.
