L-3220 Binary Pump

L-3220 is a binary gradient pump with 2-pump integration design. Developed by RIGOL’s patented technology and manufactured through advanced processing,

L-3220 owns world-class performance parameters, its operating pressure is also up to 9000PSI.
In addition to the same high-durability as L-3210, L-3220 also owns very high gradient accuracy & precision,

as well as a much lower delay volume. These features make it competent for fast & high-throughput analysis.

○ Competent for fast & high-throughput analysis    ○ Operating pressure 9000PSI    ○ Excellent gradient accuracy and reproducibility    ○ Proprietary automatic solvent-compressibility compensation technology    ○ Higher stability and longer service life    ○ Integrated damper & mixer design    ○ Online wash for piston rod
► Binary gradient pump competent for fast & high-throughput analysis, with prompt response to gradient changes and high reproducibility.
►  Max. pressure limit 9000PSI， A higher pressure limit allows a wider flexible range of chromatographic separation conditions and higher efficiency.
► Higher gradient accuracy （±0.5%）and reproducibility （≤0.15% RSD).
►  Proprietary pulsation dampening technology keeps the pressure pulsation under 10PSI, resulting in a better qualitative reproducibility.
►  High stability and durability, a longer service life.
►  Integrated damper & mixer design, provides much smaller delay volume.
► Two-pump integration design saves space and reduces delay volume, which further enables a better & faster response to gradient changes.
►  Online wash for piston rod can effectively extends the service life of sealing parts. Co-works with L-3120 solvent organizer.
