With LCD controlling system, 3 way water quality sensor, built-in 2 water tanks, 3 pump, and 2 stage RO system, Dura 12/24 series is sub-top choice of ultrapure water for high grade experiments.
With tap water inlet, its output ranges from 12 to 24 liters/hour. It can produce 2nd stage RO water and ultrapure water. The 2nd stage RO water’s conductivity can stay 1-5μs/cm, and the ultrapure water’s resistivity absolutely reaches to 18.2MΩ.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.
