The Agilent 1200 Series G1312A Binary Pump is designed for top performance high-pressure mixing.

This unit’s reliable design keeps maintenance to a minimum by using electronically-controlled active inlet-valves for flow rates up to 5.0 mL/min. Floating pistons ensure the highest seal, low internal and external volumes of capillary connections, minimum bench space needed due to two dual-piston, in-series pumps in one housing.

A wide flow range starting at typically 50 uL/min for reproducible gradients at low flow with solvent degassing.

The binary pump is based on a two-channel, dual-piston in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies which can generate pressure up to 400 bar.

Each channel comprises a pump assembly including pump drive, pump head, active inlet valve which has a replaceable cartridge, and outlet valve. Both channels are connected in a low-volume mixing chamber which is connected by a capillary coil to a damping unit and a mixer. 

A purge valve including a PTFE frit is fitted at the pump outlet for convenient priming of the pumping system.
