Yamato’s Auto Still WG205 is an economical multi-purpose benchtop high purity water purification system with 20L tank capacity. It is equipped with a pre-treatment cartridge to increase the life span of all consumables.  In addition, it displays alerts for consumable replacements and keeps track of replacement history. The WG205 produces ASTM type 1 deionized water and type 2 distilled water kept in a 20L storage tank.


  • Pre-treatment cartridge removes bacteria, trihalomethane, residual chlorine, organic and dust

  • High performance ion-exchange resin cartridge (CPC-S, 4L) brings high purity water with low electric conductivity and TOC

  • Optional membrane filter at water sampling port

  • Displays replacement of consumables

  • Equipped with automatic bolier drainage function

  • Compact. Can be installed in areas with limited space.

Stop wasting half your ultrapure water budget.
