Based on the search results, the product mentioned is likely referring to the Durapore® 0.22 µm Hydrophobic PVDF Membrane Filters (often identified by part numbers starting with GVHP, e.g., GVHP02500). While the term "Dualex-Plus" is not explicitly in the main product technical sheets, the search results highlight the Durapore® PVDF membrane, which is a key, high-performance, hydrophobic, and chemically resistant membrane. Merck Millipore +4Key Characteristics and Applications of 0.22 µm Durapore® Hydrophobic PVDF Filters:

• Membrane Type: Polyvinylidene fluoride (PVDF).
• Hydrophobicity: Hydrophobic (superhydrophobic), meaning they repel water and are suited for air/gas filtration or non-aqueous solutions.
• Pore Size: 0.22 µm, ideal for sterile filtration of gases and solvents.
• Key Features:
  • High flow rates and high throughput.
  • Low extractables.
  • Broad chemical compatibility (suitable for aggressive solutions).
  • Mechanically strong and thermally stable.
• Common Applications:
  • Air sterilization and gas venting.
  • Solvent filtration.
  • Analytical sample preparation
