Nylon 66 Membrane Filter, Hydrophilic, 0.45 µm, 25mm, PET Support, Nonsterile, 100/Pk SKU: LE-IWT-NY-045025

Featuring advanced nylon 66 polymer membrane technology delivering reliable particulate retention and superior chemical compatibility for laboratory filtration applications. Inherently hydrophilic construction eliminates pre-wetting requirements while integral polyester (PET) support layer provides enhanced dimensional stability and handling strength. Low-extractable, inert material composition ensures minimal interference with analytical protocols and sample integrity.

Key Nylon Membrane Characteristics

Naturally hydrophilic surface chemistry eliminates shelf life concerns and maintains consistent wetting properties
0.45 µm nominal pore size provides effective retention of bacteria and particulates while maintaining optimal flow rates
Excellent solvent resistance and broad chemical compatibility supports filtration of aqueous solutions and many organic solvents
High flow rate performance measured at 10 psi differential pressure using purified water at 70°F (21°C)
Capillary action associated with surface tension forces enables spontaneous water entry and efficient bulk flow through membrane pores

Key Construction Characteristics

Integral nonwoven polyester (PET) support layer reinforcement delivers added strength and dimensional stability during filtration
Standard 25mm diameter accommodates universal filter holders and laboratory filtration apparatus configurations
Strong dimensional stability and durability maintains membrane structure integrity throughout demanding filtration processes
Nonsterile designation provides cost-effective solution for routine analytical and research applications not requiring sterile media
Convenient 100-pack quantity ensures adequate supply for high-volume laboratory operations and extended analytical campaigns

LE-IWT-NY-045025 filters excel in HPLC sample preparation, microbiological testing, and general laboratory filtration protocols requiring reliable particulate removal without sample contamination. ASTM D6217 compliance¹ validates performance for particulate contamination testing in middle distillate fuels, while ASTM D5304² compatibility supports fuel storage stability assessments. Optimized for water and aqueous solutions with compatibility extending to many organic solvents, these membranes deliver consistent analytical results across diverse laboratory applications demanding both chemical inertness and mechanical reliability.
