'Quality initially, Honesty as base, Sincere company and mutual profit' is our idea, in order to create repeatedly and pursue the excellence for lab deionized water machine, Reverse Osmosis Water Systems, Type III water system. We accelerate the response of enterprises to the market by simplifying the business and new product development procedures. We always maintain a modest and prudent attitude, take the interests of customers as the core, speed as the criterion, and quality as the standard, so that customers can enjoy excellent after-sales service.
With injection molding process case, 1 pump, portable TDS test pen and on-line resistivity monitor, Smart-D series ultrapure water system is sub-economic 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
Injection molding process case Whole case with injection molding process The smallest and most compact lab water system from tap to ultrapure water, integrating pretreatment, RO, DI, UV, UF and terminal filter into one |
|
2 kinds of monitoring system On-line resistivity monitor, with apheliotropic LCD display, to detect the quality of deionized or ultrapure water. Attached portable TDS (total dissolved solid) / conductivity test pen, with dry cell design, to detect the quality of feed water and RO water. |
|
Easy-to-replacing cartridge Independent cartridges design, with fast adapters, easy to replace, and running in low cost. |
|
Whole plastic shell with high-strength Excellent ergonomic design, avoid rusting and keep clean, to meet GLP standard. |
|
Top cap of pretreatment in the case can be rapidly opened to replace the cartridges without opening the case.
System automatically works, with electronic pressure sensor and microcomputer controlling.
Automatic stop without water, automatic stop when water tank full, automatically cutting off water when pump stopping, guaranteeing 24 hours´ work.
Tube and adapter with NSF authorization and top quality, reduce TOC level and assure ultrapure water´s quality.
4 independent ultrapure cartridges with DOW´s top polishing resin, ensure ultrapure water´s quality up to 18.2 MΩ.cm, with the lowest TOC level and running cost.
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.
