Hydrophilic Nylon Membrane Filter, 0.45µm, 142mm, PET-Supported, Nonsterile, 25/Pk SKU: LE-IWT-NY-045142

Featuring hydrophilic nylon 66 polymer membrane technology delivering exceptional chemical compatibility and dimensional stability for aqueous solution filtration applications. Inherently hydrophilic, non-toxic construction eliminates the need for wetting agents while providing broad solvent resistance for both water-based and compatible organic solutions. Low-extractable, inert material supported by an integral polyester web ensures consistent performance in HPLC, microbiology, and analytical filtration protocols.

Key Nylon Membrane Characteristics

Naturally hydrophilic surface chemistry eliminates shelf-life concerns unlike cellulose acetate membranes that revert to hydrophobic states
0.45µm nominal pore size provides reliable particulate retention for microfiltration and clarification applications
Excellent solvent resistance and broad chemical compatibility supporting aqueous solutions and many organic solvents
Capillary action associated with surface tension forces enables spontaneous wetting and efficient flow initiation
Optimized for water and aqueous solution filtration with compatibility for non-aqueous fluids

Key Construction Characteristics

Polyethylene terephthalate (PET) scrim support bonded without adhesive agents maintains membrane purity and reduces extractables
Inert polyester support layer improves handling strength and helps maintain structural integrity during filtration
142mm diameter accommodates large-volume filtration systems and maximizes effective filtration area for high-throughput applications
White membrane construction with separator paper interleaving ensures easy handling and prevents membrane adhesion during storage
Recommended for ASTM D6217 particulate contamination testing in middle distillate fuels¹ and ASTM D5304 fuel storage stability assessment²

LE-IWT-NY-045142 membranes deliver exceptional 25-filter packaging optimized for laboratory efficiency, reducing inventory management while maintaining sterile handling protocols for your critical applications.
