Pure Line® Water Purifier



Yamato’s Pure Line® economical and space saving benchtop WL series water purifier connects directly to tap water. Deionized purified  ASTM type 2 water is continuously produced. The WL220T is additionally equipped with constant temperature control and has a 3L pure water tank. All units come standard with a membrane filter at the sampling port and a solenoid valve that prevents water leakage from final membrane filter. It displays alerts for consumable replacements and keeps track of replacement history.

Performance and functions

  • Collecting deionized water is as simple as connecting to a faucet
  • Benchtop, space-saving design
  • Digital display for easy operation
  • Deionized water compliant with ASTM D1193 Type 2 / JIS K 0557 A3 level, suitable for trace analysis
  • Displays replacement of consumables
  • Standard equipped with membrane filter (WL200/220)
  • A solenoid valve at the water sampling port prevents water leakage from final membrane filter
  • WL220T is equipped with constant temperature control and pure water tank. Constant temperature and deionized water delivery to pure water tank controlled by electromagnetic valve
