PES Syringe Filter w/ Glass Prefilter, 0.45µm, 13mm, Nonsterile, Luer Lock - 100/Pk SKU: LE-IWT-ES10207

Featuring high porosity asymmetric polyethersulfone (PES) membrane technology with integrated glass microfiber prefilter delivering superior sample processing for analytical and life sciences applications. The 0.45µm pore structure provides precise particulate retention while intrinsically low protein binding characteristics ensure maximum sample recovery for critical analyses. Hydrophilic membrane construction optimizes flow rates for aqueous solutions, proteins, and tissue culture media while the glass fiber prefilter extends filtration capacity by removing larger particulates before membrane contact.
