Dura Series Ultrapure Water System (Distilled Water Inlet)

Features and Advantages 

• Double stage reverse osmosis technology, assure 2^nd RO water quality´s stability from different source water.
• Built-in 3 pump- 1^st stage RO pump, 2^nd stage RO pump and circulating sanitizing pump.
• Built-in 5.8 liters PE tank and 10 liters airtight plastic pressure water tank.
• 4 door and easy-to-replacing cartridge design, convenient to maintain system and replace cartridges.
• LCD (resolution: 240×128, dimension: 106×57mm) controlling system, intuitively display the system running state and various parameters.
• 3 way online water quality sensor, detect the quality of feed water, 2^nd RO water, and ultrapure water respectively. And warn once water quality´s standard exceeding.
• Cartridges replacing alarm function, based on time and water quality, show cartridges´ used and residual life.
• Multiple alarm function: no feed water, full water, water quality´s standard exceeding, and cartridge life ending.
• Auto self-flushing of RO membrane function, extend RO membrane´s life.
• Auto running data storing function through RS232/USB communication port to computer for 1 year at least.
• System sanitizing procedure, achieve the disinfection of ultrapure water´s tube and valve.
• System circulation function, achieve ultrapure water´s circulation to keep top quality of ultrapure water.
• Level II password, protect all the parameters setting, and prohibit any unauthorized setting change.
• Water dispensing function- timing and quality (time range: 1-99min, water quality range: 0.1-18.2MΩ.cm).
• External water tanks is optional to meet different need and assure ample water-supply.
• Whole plastic shell with high-strength, avoid rusting and keep clean, to meet GLP standard.
• Tube and adapter with NSF authorization and top quality, reduce TOC level and assure ultrapure water´s quality.
• Optimized pretreatment (including PP fiber, KDF and active carbon cartridge), effectively protect RO membrane.
• RO module with DOW´s membrane, ensure long life, stable operation and high desalinization rate.
• Ultrapure cartridge with DOW´s top polishing resin, ensure ultrapure water´s quality up to 18.2 MΩ.cm, with the lowest TOC level.
• Double wavelength (185&254nm) ultraviolet lamp module, restrain bacteria´s increase and reduce TOC.
• MWCO 5000D ultrafiltration module, effectively eliminate endotoxin, and suitable for precise cell cultivating and IVF.
• (0.45+0.1)µm double layer PES terminal disinfection filter, assure that terminal pure water is absolutely axenic.

With LCD controlling system, 3 way water quality sensor, Dura series is sub-top choice of ultrapure water for high grade experiments.

With pure water or distilled water inlet, its output is up to 2 liters/minute. It can produce deionized water and ultrapure water. The deionized water’s resistivity is above 16MΩ.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.
