LabExact Nylon Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10234

At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. The nylon membrane comes in a non-sterile format for routine analytical preparation while staying stable across pH 3 to 12 and resists particle shedding through extended cycles. The polypropylene housing preserves sample chemistry across the flow path and leaves no seam for sample to bypass the membrane. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Ester- and alcohol-resistant across common laboratory sample preparations
• Synthetic polyamide backbone resists microbial and enzymatic degradation unlike cellulose membranes
• Saturation moisture uptake reaches up to 8% by resin weight
• Low extractable contribution to sensitive analytical preparations
• Polar amide backbone gives high native affinity for nucleic acids

Housing Characteristics

• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.
