LabExact Nylon Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10003

Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. Nylon delivers sharp particle cutoff at the rated pore size while withstanding elevated differential pressures and accepts water-based samples without surfactant conditioning. The PP housing sustains efficient flow on viscous samples and stands firm against aqueous acids, bases, and alcohols during regular handling. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Compatible with most HPLC mobile phases for sample clarification
• Synthetic polyamide backbone resists microbial and enzymatic degradation unlike cellulose membranes
• Filtration clarifies HPLC mobile phase buffers of particulates
• Hydrophilic surface takes up aqueous samples with no pre-wetting
• Autoclaving at 121°C for 30 minutes leaves pore structure intact

Housing Characteristics

• Medical-grade polypropylene with broad chemical compatibility
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

Sterilization Guidance

Standard autoclave cycles at 121°C for 30 minutes prepare the device for sterile workflows.
