With LCD controlling system, 3 way water quality sensors, timing and quality dispensing and 1 pump, Master-D series ultrapure water system is sub-superior 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 5MΩ.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
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 sensors, detect the quality of feed water, RO water, deionized water, or ultrapure water respectively. And warn once water quality´s standard exceeding. Water dispensing function- timing and quality (time range: 1-99min, water quality range: 0.1-18.2MΩ.cm). water. |
|
Easy-to-replacing cartridge Independent pretreatment design, and integrated subsequent purification unit design, with fast inserted adapters, easy to replace. |
|
Whole plastic shell with high-strength Excellent ergonomic design, avoid rusting and keep clean, to meet GLP standard. |
|
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 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.
External water tanks is optional to meet different need and assure ample water-supply.
3 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.
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.
