PVDF Syringe Filter, Hydrophobic - 0.45µm, 13mm, Nonsterile, Luer-Lock, 100/Pk SKU: LE-IWT-ES10048

Featuring hydrophobic PVDF membrane technology delivering exceptional chemical resistance and ultra-low protein binding for demanding analytical applications. PVDF membrane construction exhibits the lowest protein adsorption among syringe filter materials, making these filters ideal for protein solutions, oligomers, and high-value biological samples requiring maximum recovery. The 0.45µm pore size provides reliable particulate removal while maintaining optimal flow rates for sample volumes up to 10ml with minimal holdup volume below 25µl.

Key PVDF Membrane Characteristics

Exceptional chemical stability and weather resistance ensures compatibility with organic solvents, acids, and aggressive analytical solutions
Hydrophobic surface chemistry allows air and gas passage while blocking aqueous solutions, ideal for organic solvent filtration
Ultra-low protein binding membrane preserves valuable proteins and peptides during filtration processes
Broad chemical and pH compatibility withstands harsh analytical conditions without membrane degradation
Temperature resistant construction enables repeated sterilization protocols including autoclaving

Key Construction Characteristics

Luer-Lock inlet and outlet connections provide leak-tight syringe attachment for reliable sample processing
Pigment-free polypropylene housing certified for low UV-absorbing extractables ensures analytical purity
13mm diameter optimized for sample volumes 0ml-10ml with holdup volume less than 25µl minimizing sample loss
Premium polypropylene construction delivers wide chemical compatibility with molded design supporting higher operating pressures
Ultrasonically bonded assembly eliminates adhesives while clearly inscribed membrane type ensures proper filter identification

These hydrophobic PVDF filters serve as broad-purpose analytical tools widely used in HPLC applications, delivering superior performance for chromatography sample preparation and organic solvent clarification. The 0.45µm pore size effectively removes bacteria and microorganisms while meeting general chromatographic requirements for HPLC sample preparation. Nonsterile construction with excellent unit-to-unit reproducibility accelerates your analytical workflows when processing protein immunoassays, nucleic acid samples, and pharmaceutical solutions demanding both chemical resistance and minimal protein adsorption for maximum analytical accuracy.
