Waters 2410 Differential Refractometer

The Waters 2410 Differential Refractometer is a differential refractive index detector designed for high performance liquid chromatography applications. It can operate as a stand-alone unit with an integrator or chart recorder, or with a Waters system controller or Waters data system.

Features:
• Patented countercurrent heat exchanger and temperature-controlled cell for stable operation under varying conditions
• Auto zero and auto purge for automated operation
• Built-in pressure relief to protect flow cell
• Auto diagnostics
• Two external column heater controls
• Battery backup to retain parameter settings when the detector is powered off or during power interruptions
• Long-life LED light source
