Yamato PR Series Standard Gas Plasma Asher

PR200 / PR300-115V  PR300-220V / PR301-115V  PR301-220V


Standard barrel type low temperature ashing devices suitable for a wide range of application such as ashing , etching and dry cleaning


  • Isotropy barrel type
  • Compact, space saving design
  • Capable of removing coated organic matter
  • Adjustable RF suitable for various applications
  • Outstanding operability and safety
  • Can be set for a wide range of output conditions to handle a variety of testing samples


  • Functionalization of the polymeric material surface improves adhesion
  • Oxidation reaction generates functional groups -OH, >C=O, -COOH on the surface (very small amount of water and carbon dioxide will impact)
  • In nitrogen plasma, a nitrogen atom is incorporated onto the surface, generates a functional group -NH₂ Resist peeling
  • Surface modification of materials (metals, polymers, films, ceramics, etc.)
  • Asbestos pre-processing (ashing of membrane filter)
  • Low-temperature ashing (polymer material, coal, food, etc.) PDMS chips bonding to glass and PDMS substrate
  • Production of semiconductors and analysis work
