With LCD controlling system, 3 way water quality sensor, cartridge replacing alarm, timing and quality dispensing, stainless steel shell, built-in 2 set pressure tanks, single stage RO system and 1 pump, Medium-S series ultrapure water system is superior choice of ultrapure water’s mass usage for high grade experiments. With tap water inlet, its output ranges from 45 to 125 liters/hour. It can produce single stage RO water and ultrapure water. The single stage RO water’s ion rejection rate is more than 97%, 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.
