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.

Dura 12 / 24

Dura 12 / 24F

Dura 12 / 24V

Dura 12 / 24FV

Features and Advantages

Micro-computer control system with LCD display LCD (resolution: 240×128, dimension: 106×57mm), intuitively display the system running state and various real-time parameters.
Comprehensive monitoring system 3 way online water quality sensor, detect the quality of feed water, 2nd stage RO water / deionized water, and ultrapure water respectively. And warn once water quality´s standard exceeding.
Built-in 2 water tanks and 3 pumps Built-in 5.8 liters PE tank and 10 liters airtight plastic pressure water tank, save more lab space. Built-in 1st stage 2nd stage RO pump and circulating sanitizing pump.
Double stage reverse osmosis technology With 2 pumps, 2 RO membranes and buffer tank, system assures 2nd stage RO water quality´s stability from different source water, and achieves little drain and low running cost.
Easy-to-replacing cartridge Integrated design of pretreatment and subsequent purification unit. New card hawk type fast inserted interface, easy to replace.
4 door design and easy-to-maintaining Convenient to maintain system and replace cartridges.

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.
