This is a refurbished Agilent 1200 Series G1312A Binary Pump.
The Agilent 1200 G1312A Binary Pump is a high-performance, binary pumping system for use in liquid chromatography. It features a compact design and operates using a binary pumping mechanism, which allows for high pressure operation and efficient sample delivery. The pump features a high-resolution, low-pulsation flow rate, making it ideal for use in demanding applications.
| Type | Specification |
| Hydraulic system | Two dual piston in series pumps with proprietary servo-controlled variable stroke drive, floating piston design and active inlet valve |

| Control and data evaluation | Agilent Chem Station for LC |
| Analog output | For pressure monitoring, 2mV/bar, one output |
| Communications | Controller-area network (CAN), GPIB, RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional |
| Safety and maintenance | Extensive diagnostics, error detection and display (through handheld controllers G4208 A, G1323 B and Agilent Chem Station), leak detection, safe leak handling, leak output signal for shut down of pumping system. Low voltage in major maintenance areas |
| GLP features | Early maintenance feedback (EMF) for continuous tracking of instruments usage in terms of seal wear and volume of pumped mobile phase with user-settable limits and feedback messages. Electronic records of maintenance and errors. |
| Housing | All materials recyclable |
