Master-Q Series Deionized Water (DI water) System (Tap Water Inlet)

Features and Advantages

Master series is the sole leading brand of Chinese Good Instrument in lab water area. It is the most representative products in

Chinese lab water market.

 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, RO water, deionized water, or 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 (optional).

 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.

 3 door 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.

 4 in 1 ultrapure cartridge (can be divided to 4 independent 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.




Master-Q series deionized water system is superior choice of deionized water for general grade experiments. Withtap water inlet, its output ranges from 15 to30 liters/hour. It can produce single stage RO water and deionized water. The single stage RO water’s ion rejection rate is more than 96%, and the deionized water’s resistivity is more than 16MΩ.cm, near to18.2MΩ.cm. It completely meets the requirements of general chemical or biological experiments for pure water.
