PES Syringe Filter w/ Glass Fiber Prefilter, Nonsterile, 0.22µm, 25mm, Luer-Lok, 100/Pk SKU: LE-IWT-ES10208

Featuring hydrophilic polyethersulfone membrane technology with integrated glass microfiber prefilter delivering exceptional flow rates and superior sample recovery for demanding laboratory applications. The high porosity asymmetric pore structure provides intrinsically low protein binding while the glass fiber prefilter dramatically increases particle loading capacity and extends operational life. Operating temperature tolerance to 60°C with broad chemical compatibility accommodates diverse analytical protocols requiring maximum throughput and minimal sample loss.

Key PES Membrane Characteristics

Hydrophilic polyethersulfone construction with intrinsically low protein binding characteristics maximizes recovery of valuable biological samples
0.22µm absolute pore rating delivers reliable sterile filtration and particle removal for critical applications
Exceptional compatibility with acids, bases, and oxidizers enables processing of challenging sample matrices
Glass microfiber prefilter increases dirt-holding capacity by 300% while preventing membrane fouling during high-particulate sample processing
Ultra-low extractables profile maintains sample integrity for sensitive HPLC, ion chromatography, and GC analysis protocols

Key Construction Characteristics

Ultrasonically bonded polypropylene housing with female Luer-Lok® inlet and male slip outlet ensures leak-free operation under pressure
25mm diameter membrane provides 4.08 cm² effective filtration area optimizing flow rates for routine laboratory volumes
Concentric funnel-shaped barrel design increases sample volume capacity while reducing back pressure during filtration cycles
Filter media type clearly inscribed on barrel enables rapid identification and prevents cross-contamination errors
Individual blister packaging maintains cleanliness and enables convenient single-unit dispensing in sterile work environments

LE-IWT-ES10208 filters achieve outstanding unit-to-unit and lot-to-lot reproducibility ensuring consistent results across extended analytical campaigns. The integrated glass fiber prefilter transforms these units into high-capacity sample preparation tools, accelerating your filtration of tissue culture media, protein solutions, buffer preparations, and nucleic acid samples requiring both particle removal and bioburden reduction. Certified ion chromatography compatibility delivers validated performance for your most demanding analytical applications while the nonsterile format provides cost-effective processing for routine laboratory filtration protocols.
