Operating Recommendations

The typical cause of failure at the rotor seal is wear of the Vespel material. A major cause of wear is the use of buffered mobile phases. To help improve the lifetime of the rotor seal it is recommended that the system and injection valve be flushed with either the mobile phase without the buffer addition or with an aqueous solution. Be sure to toggle the valve through both the bypass and inject positions to flush all of the mobile phase salts from the injection port.

Installation Information

Sciencix parts are designed to be compatible and interchangeable with OEM parts. Please see instrument service manual for proper removal and installation procedure.

Replacement Frequency

The rotor seal generally is not part of a required maintenance protocol. Indications that the rotor may need to be replaced are poor reproducibility of injection volume or a leak at the injection valve.
