This is a used Waters Prep HPLC 2535 Quaternary Gradient Module.

The Waters Prep 2535 Quaternary Gradient Module is a four solvent, low pressure mixing gradient pump (up to 50 mL/min) that serves as a solvent delivery device for purification systems. Dual programmable flow paths enable the system volume to change when the column size is changed.


  • Four-solvent gradient selection
  • Two fluidic pathways (small scale and large scale) to accommodate column selection and chromatographic efficiency
  • Interfaces to a variety of detectors and peak fraction collectors for optimum purifications
  • Allows UV- or MS- directed purification with MassLynx Software
  • Leak detection is standard
  • 50 mL/min capability for using columns up to 30 mm I.D. for purification of milligrams of material
  • Many optional shelf units, degassers, splitters, and accessories to customize any system
  • High pressure operation @ 6,000 psi (414 bar) to accommodate a wide variety of column lengths, diameters, and particle sizes
