How Filtration Membranes Work

Membrane filters are partially permeable. They allow some molecules to pass, but not others. As a rule, pore size determines molecule selectivity. Membrane thickness is also important to consider because thinner filter membranes may require a support material.

Filtration Membrane Materials and Applications

Filtration membranes may be composed of nylon, polypropylene, cellulose, nitrocellulose, glass fiber, and PTFE.

  • Nylon filtration membranes are chemically compatible with a wide range of solvents.
  • Polypropylene filtration membranes are used with more aggressive solvents. Because these membrane filters are highly adsorbent, they’re also a good choice for high performance liquid chromatography (HPLC) applications with low detection levels.
  • Cellulose acetate filtration membranes are used in diagnostic cytology and the filtration of enzyme solutions.
  • Nitrocellulose filtration membranes are used in for laboratory applications such as nucleic acid and protein detection.
  • Glass fiber membrane filters are made of pure borosilicate and used to measure suspended solids. Some borosilicate fibers feature fine porosity and can tolerate high temperatures.
  • PTFE membrane filters can have hydrophobic or hydrophilic characteristics. Hydrophobic PTFE membrane filters are used to sterilize gases and aggressive chemicals. Hydrophilic PTFE membrane filters are recommended for HPLC.

How Filtration Membranes Are Manufactured

Interstate Specialty Products die cuts filtration membranes from sheets or rolls of sourced materials based on the specifications above. We can also work with customer supplied materials and convert your purchased materials into precise components. Cleanroom die cutting is recommended for sensitive medtech and pharmaceutical applications.
