These cartridges are designed to meet the special needs of the electronics and high purity chemical industries.  Each cartridge is power rinsed and flushed to ensure minimal extractables and no manufacturing debris:

• EPS grade Polyethersulfone Membrane Media Filter Cartridges (PDF)
  Polyethersulfone membrane cartridges are resistant to most acids and bases and capable of handling oxidizing agents.  High flow rate makes Polyethersulfone a good choice for central DI water systems.
  
• ENM grade Nylon Membrane Media Filter Cartridges(PDF)
  Able to remove particles below the rated pore size of the membrane, these cartridges exhibit superior retention.  Often used for DI water, photoresist, developers and other compatible chemicals.

• EPD grade Polypropylene Depth Media Filter Cartridges (PDF)
  This cartridge produces minimal extractables when exposed to typical process chemical and solvents.
  
  
• EPM grade Polypropylene Membrane Media Filter Cartridges (PDF)
  This cartridge produces minimal extractables when exposed to typical process chemicals and solvents.  These membrane cartridges should be used when absolute retention is essential for the process.
   
• ETM grade PTFE Membrane Media Filter Cartridges (PDF)
  ETM cartridges are designed to meet the special needs of the electronics and high purity chemical industries. Teflon membrance cartridges are resistant to virually all chemicals.
