Model: RODI-2000-03B - High Flow Type I Biological Grade RO+DI System

This combination Reverse Osmosis System and 8-12 Liters/minute DI System is utilized in operations involving virtually any quality tap water. The system is mounted on a welded aluminum frame and includes a built-in three stage pre-filter assembly. The RO portion of the system will economically remove >97% of the contaminants from the incoming water, and will produce RO pretreated water at the rate of ~ 2-GPM.

The RO water is stored in a 200-Liter pressurized storage tank for use by the DI portion of the system. The pressurized tank eliminates the risk of airborne contamination and the need for a feed pump. The DI portion of the system produces up to 18.2-Megohm-cm water that is free of Pyrogen, Endotoxin, RNase and DNase at a flow rate of 8-12 Liters/minute.

DI water production is limited by the storage capacity and RO production. This system features continuous recirculation to maintain maximum water purity and a digital conductivity/resistivity meter to monitor the DI water quality. The meter has a green LED to indicate that the water quality is acceptable and a red LED that alerts the user when the water quality drops below the desired level.

More Information

All AQUA SOLUTIONS Biological Grade Type I DI Laboratory Water Purification Systems produce purified water that meets or exceeds ASTM, CAP and CLSI specifications for Type I reagent grade water. Since ordinary tap water contains 5-25 times the impurities of pretreated water, these tap water systems have lower overall capacity than pre-treated water systems.

Features and Benefits:

  • Ultrafilter removes Pyrogen, Endotoxin, RNase and DNase
  • High ion exchange capacity (6,000-12,000 Grains) CaCO3 to a 0.02-Megohm end point
  • Continuous recirculation is utilized to ensure water quality and prevent the growth of microorganisms within the system
  • Final filtration of 0.22 µm capsule (Part# - DC2022)
  • One (1) year system warranty
  • This item is on our GSA Contract # GS-07F-5799R
  • Made in USA
