Shimadzu Low Pressure Valve Rotor Seal for Shimadzu SIL-40 series, SIL-30AC, SIL-30ACMP

The Shimadzu 228-71780-43 is a high-performance Low Pressure Valve (LPV) Rotor Seal designed for the rotary valves found in Shimadzu's premier autosampler lines. This seal is a critical wear part that ensures the sample aspiration and washing cycles remain leak-free. This seal is manufactured from a specialized PEEK/PTFE composite for high chemical resistance and low friction.

The main function of this seal is to act as the interface between the rotating valve body and the stationary stator, directing the flow of solvents and samples during the pre-injection phase. This critical consumable ensures the precise switching of solvent and sample paths at lower pressures before the final high-pressure injection stage.

Used; good condition.
