  • PTFE membrane is a natural hydrophobic media, if used for high surface tension fluid filtration, it's necessary to pre-wet the filter cartridge or directly use pre-wetting products.
  • Pre-wetting products are conserved in the mix of ultrapure water and hydrogen peroxide, drain the internal liquid and rinse with 20L (every 10 inch unit) pure water before installation and use.

Pre-wetting Regulation

  • Fully immerse cartridge into wetting liquid(IPA:Wa-ter=60:40) for 30 min
  • Soak in ultra-pure water for 5 minutes
  • Use ultra-pure water to rinse for 20min @ 7.5LPM(filter fully exhaust, cartridge is completely immersed in pure water.
