Yamato Pure Line WE200 Lab Water Purification System


Yamato’s Pure Line WE200 benchtop water purification system has an integrated reverse osmosis membrane cartridge to increase the life span of all consumables significantly. The standard equipped membrane filters additionally protect pure water production from contamination. It displays alerts for consumable replacements and keeps track of replacement history. The WE200 produces ASTM type 1 deionized water and is suitable for high sensitivity analysis.


  • Suitable for high sensitivity trace analysis

  • Lower running cost

  • By adopting reverse osmosis (RO) membrane cartridge set, life span of consumables has been expanded significantly

  • Benchtop type, space saving

  • Easy water sampling by attaching to water faucet

  • Easy to operate digital display

  • Displays replacement of consumables and its exchange history

  • Standard equipped with membrane filter to protect pure water production from contamination

  • Electromagnetic valve equipped at sampling water port for leakage prevention

  • Universal power supply: works with 100-240VAC

Stop wasting half your ultrapure water budget.
