RSLCnano Pump with Column Compartment

Enter the new dimension in Nano LC with the NCS-3500RS. All in a single housing, this module provides a binary high-pressure gradient RSLCnano pump, a ternary low-pressure gradient loading pump, and a column compartment for shortest possible capillary connections and highest application flexibility. The module covers the widest flow range from 20 nL/min to 50 µL/min at pressures up to 800 bar (11,600 psi). The robust, continuous direct flow delivery is designed for interruption-free analysis and industry-leading retention time precision.

RSLCnano HPG Pump

The RSLCnano HPG pump is a high-pressure gradient (HPG) pump for nano, capillary, or micro flow delivery, featuring continuous direct-flow delivery from 20 nL/min to 50 µL/min at pressures up to 800 bars. Available as a stand alone pump (NCP-3200RS) or a dual-gradient pump and column compartment in one housing (NCS-3500RS).

Binary Rapid Separation LC Pump

The Binary Rapid Separation Pump HPG-3x00RS is with its industry-leading performance and reliability the best choice for any ultrahigh-speed and ultrahigh-resolution application.
