Agilent Cartridge Inlet Check Valve 5/10/25 mL, R007101408 (New)

It ensures unidirectional flow of the mobile phase into the pump while preventing backflow, maintaining stable pressure and flow rates during chromatographic operation.

Each valve cartridge features a precision sapphire ball and seat assembly for superior sealing, chemical resistance, and long-term reliability under high pressure. The low-dead-volume design minimizes pulsation and supports accurate solvent delivery, contributing to reproducible and stable HPLC performance.

Regular replacement of the inlet check valve is recommended as part of preventive maintenance, especially if flow instability or pressure drop is observed.
