The serial-piston GS50/IS25 pumps provide gradient and isocratic eluent delivery at lower flow rates.Maximize Your Investment to Support a Broad Range of Applications- All-PEEK flow paths to support all ion chromatography applications; compatible with pH 0–14 and most reversed-phase eluents
- Easy conversion to low delay volume configuration that provides excellent “sweep-through” and accurate, sharp gradients
- Program isocratic blending, or binary, ternary, or quaternary gradients; four concave and four convex gradients are available
Achieve Your Requirements for Best Analytical Performance
- Flow rate range of 0.05–5.00 mL/minute to provide the best accuracy and precision over the core analytical flow rate range
- Low-pressure ripple without mechanical pulse damper; smooth flow combines with low delay volume for high-sensitivity detection
- Accurate, low-pressure proportioning over the entire 0–100% range for precise delivery of even the most demanding gradients
- Built-in vacuum degas option that provides sealed, pressurized, in-line degassing for enhanced reproducibility; also protects eluents from exposure to atmosphere
Minimize Operational Costs and Maximize Usage with Inert, Rugged Construction
- Inert PEEK flow components for rugged high-pressure mobile phase delivery
- Proven performance of PEEK
- Front access to all maintenance parts for fast, easy replacement
- An optional continuous piston wash that prolongs seal lifetime by preventing seal crystallization
