B2300 Binary Pump

Meets the Most Demanding Applications

The B2300 series consists of two high-performance pumps, dual pulse dampers, and an offline pressure transducer.
Pump features:
- Fast & easy setup — 2 inlet connections from solvent reservoirs, outlet connection to injector
- Modular — can be added to any system
- All stainless or PEEK fluid path (pumps, valves, and fittings)
- Self-flushing pump heads for extended seal life and reduced maintenance
- Overpressure system shutdown to protect LC column
- Easily user-adjusted process set points (flow rate, pressure) via front keypads
- Digital readout of process parameters
- User-settable upper/lower pressure limits
- RS-232 interface
- USB Connectivity (integrated USB to RS-232 Solution
- Compact size — 11 inches wide
- .001-5 mL/min or .01-10 mL/min flow ranges

Reduced Maintenance

Seal life is dramatically extended by actively flushing the back of the primary seal with a flushing solution. The result is less down-time and reduced operating expenses. The self-flush is automatic—just change the flushing fluid weekly. Seals can be changed in five minutes without tools.

New Easy Prime Heads

The B2300 Pump features a head design with the prime purge valve integrated into each fluid path. This insures the solvent is drawn from the reservoir even if the other pump is running.

Simple, Effective Gradient Control

Binary gradient programming is accomplished by a hand-held keypad unit.

Performance and Reliability Beyond its Price

The use of digital stepper motor technology and the proven single-piston design gives the performance of the most expensive pumps at a fraction of their cost. The operating cost is lower too, due to the simplicity of the design and fewer number of parts required. It’s so reliable it carries a three-year warranty.

Reproducibility You Can Count On

The B2300 Pump gives reproducible gradients and chromatography due to its pulse free low volume fluid path.
The result of this simplicity and low dead volume is reproducibility that is seen in the chromatographic performance.
