Both-Ends-Selected Flowpath Selectors - High Pressure

ST selector flow schematic

ST selectors are used for multi-column, multi-sample, or multi-trap operations. This valve can be used between an injector and detector to permit manual or automated HPLC column selection.

High pressure ST selectors are made of Nitronic 60, with a rotor made of Valco E, a polyaryletherketone/PTFE composite. Valves are rated for 5000 psi liquid at 75°C.

Valves can be actuated manually or automated with pneumatic or electric actuators. HPLC valves don't usually require a standoff, but they are offered, in lengths of 2", 3" 4", and 6".
