RO (reverse osmosis) is the most economical method to remove up to 99% of your water's impurities. The RO membrane is semi-permeable with a thin microporous surface that rejects virtually all dissolved materials including dissolved inorganic solids, organics, particles and microorganisms.

Barnstead RO system provides a source of purified water for general lab use such as glassware washing or as feed water to our ultrapure water systems such as the Nanopure and Easypure.
