Sterile PES Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 25mm, Hydrophilic, 100/Pk SKU: LE-IWT-ES10213

Featuring dual-layer polyethersulfone membrane technology with integrated glass microfiber prefilter delivering exceptional sample throughput and sterile processing capabilities. The glass fiber prefilter reduces the particle loading experienced by the membrane final filter and, consequently, extends the service life. PES is hydrophilic and constructed from pure polyethersulfone polymer membrane for maximum sample recovery. Low protein and drug binding characteristics make it ideally suited for use in life sciences applications. Advanced gamma sterilization processing ensures sterility integrity while maintaining optimal filtration performance for critical laboratory applications.
