Dura series water purification system

Features and Advantages
● Double stage reverse osmosis technology, assure 2nd RO water quality’s stability from different source water.
● Built-in 3 pump- 1st stage RO pump, 2nd 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, 2nd 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.

Dura 12/24 series ultrapure water system (tap water inlet)
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.
