The Agilent 1200 Infinity Binary Pump G1312B provides a flexible platform for binary gradient chromatography that can be adapted to different analytical requirements. Its standard high-pressure binary mixing architecture can be expanded with an optional four-inlet Solvent Selection Valve, Active Seal Wash for prolonged use with concentrated buffers, or an external vacuum degasser for applications requiring maximum flow and retention-time stability.
