The MEDICA range of laboratory water purification systems for clinical analyzers, from Siemens Water Technologies, delivers CLRW grade water (clinical laboratory reagent water) to clinical chemistry and immunodiagnostic analyzers. MEDICA water systems come in a choice of models and flow rates to meet clients' unique requirements. The MEDICA S/R/D (7/15) is a compact system using pretreatment, reverse osmosis, deionization, UV photo oxidation, and microfiltration to produce CLRW-grade water for low-volume clinical analyzers. The MEDICA Pro S/R/RE (30/60/120) has a 50-L, built-in water storage reservoir and long-lasting deionization cartridges; it features a space-saving design that can be upgraded for higher flow rates. The MEDICA R-200 is designed to supply up to 16L/min of CLRW water to higher-volume analyzers, or multiple clinical analyzers in a loop.
