LabExact Nylon Syringe Filters, 0.45 µm, 4 mm, 200/Pk - LE-IWT-ES-10602

Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. The nylon matrix holds consistent retention across mixed-phase samples while staying stable across pH 3 to 12 and resists particle shedding through extended cycles. Polyolefin construction sheds virtually no extractable material into the sample and routes flow to minimize backpressure in service. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Synthetic polyamide backbone resists microbial and enzymatic degradation unlike cellulose membranes
• Moisture-plasticized amide linkages raise membrane impact toughness over dry resin
• Saturation moisture uptake reaches up to 8% by resin weight
• Filtration clarifies HPLC mobile phase buffers of particulates
• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis

Housing Characteristics

• Thermal-bonded construction keeps adhesives out of the fluid path
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Stable across the full aqueous pH range in routine sample work

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification. Request blanket-order pricing and paperwork support for your routine filtration purchases.

Sterilization Guidance

The housing supports customer autoclave sterilization at 121°C for 30 minutes.
