HOMEProductsPlasma Cleaner, AsherPR300/301
Low Temperature Asher

  • Three 64mm diameter chambers are included. (PR300)
  • The unit can be set for a wide range of output conditions to handle a variety of testing samples.
  • One 118mm diameter large chamber is accommodated.
The PR 300 is a gas plasma device that is used widely for such applications as production of semiconductors and analysis work. It boasts outstanding operabi lity and safety, with an automatic tuning system as a standard component and other features. It has a compact design, with a small-size HF generator and an oscillation section integrated with a portion of the chamber, allowing it to be installed into a 19-inch rack.
