The advantages of the DuoPUR system


    Cost comparison
  • Save up to 90 % of the cost of ultrapure acids by purifying low cost reagent grade acid.
  • Works with HN03, HCl, H2SO4, H2O; also suitable for purification of organic solvents
  • Up to 4.5 L of ultrapure acid in 6 hours
  • Re-purify reagents that have become contaminated
