Designed for laboratories requiring high-purity water from standard tap water, the WG205 features easy-to-replace consumable cartridges, a built-in 20L storage tank, and automatic boiler drainage — all in a space-saving footprint.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduces both deionized (ASTM Type 1)
