Reverse osmosis systems are essential pre-treatment units for laboratory water purification, capable of removing up to 99% of dissolved solids, bacteria, and organic compounds. These systems use semipermeable membranes under high pressure to purify tap water before it enters pure or ultrapure systems. RO systems improve overall system efficiency, protect downstream components, and extend the lifespan of polishing cartridges. They are widely used in laboratories, clinical diagnostics, and industrial water treatment processes.
