The Yamato WG-205-220V is an Auto Still® laboratory water purifier that produces both deionized and distilled water by ion-exchange → distillation, delivering ~1.5 L/h of distilled water into a 20 L tank on AC220V, 6 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 consumable-replacement indication.
