Agilent Cartridge Outlet Check Valve 5/10/25 mL, R007101409 (New)

It maintains unidirectional flow of the mobile phase from the pump to the column while preventing backflow and pressure loss.

Each valve cartridge features a precision-engineered sapphire ball and ceramic seat housed in a stainless steel body for high-pressure performance, tight sealing, and long service life. The low-dead-volume design minimizes pulsation and enhances flow stability, ensuring accurate and reproducible solvent delivery — essential for consistent chromatographic results.

Routine replacement of the outlet check valve is recommended during preventive maintenance when signs of pressure fluctuation, flow inconsistency, or unstable baselines are observed.
