Dura Pro series, integrating 5.0 inch touch screen system, 3 way water quality sensors, 2 way flow sensors to achieve quantified dispensing, built-in 1 buffer water tank, 3 pumps, and 2 stage RO system, its output ranges from 12 to 24 liters/hour with tap water inlet. Moreover, it equips the remote portable dispenser and 50 liters tank as standard configuration.

It can produce 2 kinds of pure water- deionized water and ultrapure water. And the third kind of pure water-2nd stage RO water is optional.

The 2nd stage RO water´s conductivity can stay 1-5μs/cm. 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.
Features and Advantages

Colorful touch screen

5.0 inch colorful high-resolution touch screen (16:9) controlling system, achieve finger-touch new experience.

Comprehensive monitoring system

3 way online water quality sensors, detect the quality of feed water, RO water, deionized water, or ultrapure water respectively。 And warn once water quality´s standard exceeding。

2 way flow sensors, achieve quantified dispensing of RO water, deionized water, or ultrapure water.

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.

2 pure water outlets-Deionized & Ultrapure water

Equipping built-in mixed bed resin cartridge and ultrapure polishing resin cartridge, to achieve that the deionized water´s resistivity is above 16MΩ。cm, and the ultrapure water´s resistivity absolutely reaches to 18。2MΩ。cm。

Standard equipped remote portable dispenser

2。0 inch colorful graphics display, acrylic panel, online monitoring the resistivity, temperature, flow rate and dispensed volume of pure water, 2 dispensing models-Instant and volume dispensing, easy for single hand operation, height adjustable arm, more user-friendly as Pipette-type dispensing, system circulation function, to achieve ultrapure water´s continuous circulation, suitable for all lab dispensing such as glassware or volumetric flasks etc。

Standard equipped 50 liters tank

100% PE material, the smooth internal surface, conical bottom, standard equipped air filter could absorb CO2 and organics, and eliminate bacteria and particles. UV lamp is optional to restrain bacteria´s increase and reduce TOC.

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.

All Cartridges replacing alarm function, based on time, or 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 (interval and continuous time setting), extend RO membrane´s life.

Comprehensive Information query and management function, master system status, water quality, cartridges usage and alarm information.

System time setting (year/month/day/hour/minute), timing standby (0-60 minute), and timing shutdown (0-24 hour) function.

Level II password, protect all the parameters setting, and prohibit any unauthorized setting change.

Auto running data storing function with built-in SD card, and data can be exported through the USB interface.

Whole plastic shell with high-strength, avoid rusting and keep clean, to meet GLP standard.

4 doors and easy-to-replacing cartridge design, convenient to maintain system and replace cartridges.

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.
