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.
