Setable Flow Range
Setpoints 0.001 – 5 ml/min, in 0.001 ml/min increments
Flow Range
0.1 – 5.0 ml/min
Pressure Range
0 - 400 bar (0 – 5880 psi) up to 5 ml/min
- Features a two-channel, dual-piston in-series design.
- Comprises all essential functions of a solvent delivery system.
- Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies.
- Variable stroke volume allows pulse-free solvent delivery and efficient mixing.
- Active inlet valve synchronized to piston stroke eliminates vapor formation with volatile solvents and is maintenance-free.
The Agilent G1312B SL Binary Pump features a two-channel, dual-piston in-series design which comprises all essential functions of a solvent delivery system. 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, 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. The design of the 1200 G1312B SL with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke-eliminates vapor formation with volatile solvents and is maintenance free.
All of our equipment will be fully tested to perform at factory specifications before being shipped.
