Sterlitech Polyethersulfone (PES) Membrane Filters - PES0814220

These hydrophilic, low protein binding, Sterlitech PES (Polyethersulfone) Membrane Filters are ideal for tissue culture media sterilization, life science and microbiology fluid applications, clinical, and general filtration.

  • Strong and durable for easy handling
  • Lot-to-lot consistency provides reproducible results every time
  • Uniform pore structure
  • Low protein binding
  • Compliant for food contact under the applicable regulations in 21CFR177

Microporous PES membranes are produced from a high-temperature, acid and base resistant, polyethersulfone polymer in a proprietary, quality-assured manufacturing process. The high level of quality standards applied in each step of production provide consistent products with pore uniformity for predictable flow rates, particle retention, and purification values. Inherent, uniform porosity and controlled pore size allow these PES filtration membranes to efficiently remove particulates from solutions during general filtration and its low protein and drug binding characteristics maximize recovery of critical drugs used in IV therapy, chemotherapy, and open-heart surgery. The strength and durability offered by our PES membranes is suited for aggressive handling and use with automated equipment. To accommodate the diverse needs of our customers, this unique membrane technology can be purchased in a variety of pack sizes of pre-cut discs, sheets, or rolls with pore sizes ranging from 0.03 to 5.0 µm; large enough to provide the high capillary flow rates required by lateral flow assays and other diagnostic devices.

0.03 µm, 5.0 µm and 8.0 µm pore sizes are also available.
