Yamato WG Series Auto Still Lab Water Purification System


Yamato’s Auto Still multi-purpose water purification system come standard with water intake membrane filters to increase the life span of all consumables and a 30L(WG252) or 100L (WG1012) large storage tank capacity. The standard equipped membrane filters at feeding port protect pure water production from contamination. The WG series produces ASTM deionized water type 1 and type 2 distilled water kept in a 30L or 100L storage tank.


  • Two independent dispensers for water sampling

  • 7-inch LCD touch panel system

  • Consumable management functions

  • Trend graph

  • Easy replacement of ion-exchange resin

  • Large distilled water tank with capacity of 30L (WG252) and 100L (WG1012)

  • Easy to use slide out type water sampling tray with drainage eliminates concerns about overflowing water discharge

Stop wasting half your ultrapure water budget.
