PES Syringe Filter

Polethersufone (PES) membrane for aqueous solutions provides removal of fine particles, bacteria, viruses, and fungi, making it a versatile membrane for applications such as sample preparation, sterile filtration and infusion therapy. PES is an inherently hydrophilic membrane that wets out quickly and completely, resulting in fast filtration with superior flow rates and high throughputs. The hydrophilic nature of PES means no added surfactants are used to increase wettability. PES membrane is also extremely low protein binding, minimizing the likelihood of target analyte binding. Polyethersulfone membrane is compatible with EtO, gamma irradiation, and autoclave methods of sterilization.

The low protein binding nature of the polyethersulfone membrane makes it well suited for biological sample preparation. Available in a variety of pore sizes, the membrane can be used for coarse particulate removal in prefiltration applications or as a fine final filter for clarification. An excellent choice for bead-based, multiplexed assays, the PES membrane yields high microsphere recovery and reduces the incidence of false positives in serological assays.
