Can Lint-Free Wipes Filter Alcohol?

1. Filtration Mechanism of Lint-Free Wipes

• Material Structure:

  • Ultra-fine fiber weave (0.5-5μm pores)

  • 3D network architecture

• Filtration Principles:

  • Mechanical interception: Blocks particles (≥1μm)

  • Electrostatic adsorption: Captures sub-micron particles

2. Alcohol Filtration Feasibility

✅ Filterable Components:

• Suspended particles (metal debris/dust)

• Microorganisms (bacteria/fungi)
  ❌ Non-Filterable:

• Alcohol molecules (ethanol diameter ≈0.44nm)

• Dissolved contaminants (ionic impurities)

3. Professional Alcohol Filtration Solutions

1. Material Selection:

   • Glass fiber wipes (alcohol-resistant)

   • Multi-layer composite (pre-filter + fine-filter)

2. Operating Parameters:

   • Flow rate: <10ml/min/cm²

   • Filter area: ≥2× container diameter

4. Applications & Limitations

• Suitable Uses:

  • Lab alcohol pre-purification

  • Industrial alcohol recycling

• Prohibited Scenarios:

  • Medical-grade sterilization (requires 0.22μm membrane)

  • High-purity electronic alcohol production

5. FAQs

Q: Does filtration alter alcohol concentration?
A: No, but volatility increases (store sealed)

Q: Can wipes replace filter paper?
A: Only for coarse filtration; use membranes for precision
