Spectra/Chrom® S-3 Solvent Saver System

Make your Acetonitrile Supply Last Longer

  • Saves up to 90% of acetonitrile and other solvents in HPLC applications
  • Saves on solvent purchases
  • Saves on recycling costs
  • In stock and ready to ship

The S-3 Solvent Saver System is a microprocessor-controlled system Which reduces the amount of solvent, including acetonitrile, used in HPLC applications by up to 90%. The system allows solvent between peaks to be recycled. Use of the S-3 saves on solvent purchases while reducing the amount of toxic waste generated. The S-3 Solvent Saver System works with both UV and RI detectors and can be operated both manually and automatically. The system is CE marked and complies with RoHS.

The programmed level may be positive only (for use with unipolar detectors like UV absorbance monitors) or both positive and negative (for use with bipolar detectors like RI monitors). The Solvent Saver can handle up to a 50% overrange and continuously displays its status and the signal level. The recycle valve can also be set manually or by remote control to remain in either the recycle or waste position. A Q.A. validation signal continuously indicates the valve's position.

The Solvent Saver comes complete with the control console, valve, a signal cable, and fittings for 1/16" OD and 1/8" OD tubing.
