Laboratory Water Purification Systems

Yamato Scientific water purification systems deliver everything from point-of-use deionized water to Type I ultrapure (18.2 MΩ·cm) reagent water for the most demanding analytical and life-science work. LabSupplies.com is an authorized Yamato dealer offering the full range — modular Type I systems, Auto-Still® distillation purifiers, RO/DI systems, and cartridge DI units.

Type I ultrapure systems (WA / WB / WC / WG)

A modular platform delivering 2.5 LPM of 18.2 MΩ·cm Type I water on demand, with real-time quality monitoring, leak detection, and quick-change ResinTech cartridges. Choose the modules your work needs:

• WA — base system: conditioning + polishing cartridges, 0.2 µm filter (TOC < 15 ppb).
• WB — + ultrafiltration: adds pyrogen removal and nuclease-free water.
• WC — + UV oxidation: adds bacteria sterilization and TOC reduction (TOC < 5 ppb); for organic and analytical chemistry. UVT adds a TOC monitor.
• WG — fully loaded: UV + UF together for genetics and biological work; UVUFT adds a TOC monitor.

Each is available as benchtop/wall-mount or remote-dispense, in 120V (301) or 220V (311).

Auto-Still® distillation purifiers (WG-205 / 253 / 1013)

• WG-205 — ion-exchange + distillation, ~1.5 L/h, 20 L tank.
• WG-253 — + filtration, 30 L tank, separate DI and distilled dispensing.
• WG-1013 — high-capacity ~5 L/h, 100 L tank.

RO/DI and cartridge systems

• WE-200 — RO membrane + ion-exchange DI, 0.5–1.0 L/min, ASTM Type I / JIS A4.
• WH series — compact cartridge DI systems in high-capacity (WH-201C) or high-purity (WH-201P) configurations, 2.5" or 4.5" cartridges.
