Injection Valves

Injection Valves

Agilent's industry-leading Manual Injection Valves are designed to ensure trouble-free operation with your HPLC System. Valves feature patented "Make-Before-Break" architecture that allows switching between LOAD and INJECT positions without interrupting flow, so more samples may be analyzed in less time. A variety of injection valves are available with different position and port injections, and delivering effective operation under different pressures, to ensure you can choose the right injection valve for your system and application. Various rotor seal material types are utilized in the injection valves, with rotor seals made of Vespel, Tefzel and PEEK, depending on sample pH.
