The Yamato WG-253-115V is an Auto Still® laboratory water purifier that produces both deionized and distilled water by ion-exchange → distillation → filtration, delivering ~1.5 L/h of distilled water into a 30 L tank on AC115V, 11 A, 50/60 Hz (with external transformer). A pre-treatment cartridge removes bacteria, trihalomethane, residual chlorine and organics ahead of a hard-glass condenser and ion-exchange polishing, with a 7-inch LCD touch panel for consumable management and water-quality trend graphs.
