LabExact PVDF Syringe Filters, 0.45 µm, 4 mm, 200/Pk - LE-IWT-ES-10608

A syringe filter dispenses filtrate directly into an autosampler vial, without the intermediate collection vessel a bulk vacuum filtration setup typically needs. The PVDF membrane clarifies samples at the rated pore size while tolerating common chromatography solvents without degradation and repels water for dependable gas and vent filtration. Polypropylene construction maintains a low-dead-volume internal flow path and leaves no seam for sample to bypass the membrane. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Mechanically durable membrane holds integrity under filtration pressure
• Organic solvent resistance beats PES or nylon at comparable pore size
• Ethylene oxide sterilization cycles leave pore integrity and flow performance intact
• Absolute pore rating ensures reproducible results between test runs
• Fluoropolymer chemistry resists microbial and fungal degradation

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Stable across the full aqueous pH range in routine sample work
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Optimized internal geometry minimizes backpressure in service

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Reliable solvent prefiltration keeps a stray particulate from carrying into your downstream work from reaction mixtures and crude extracts through further processing.

Sterilization Guidance

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

• Robust Particulate Filtration - Withstands high pressure differentials while handling heavy particulate loads, extending membrane service life.
• Petroleum Sample Prep - Removes particulates from fuel and lubricant samples ahead of viscosity and quality-control testing.
• QuEChERS Extract Prep - Removes co-extracted waxes and pigments from QuEChERS extracts, protecting GC-MS and LC-MS systems during pesticide testing.
• Beverage QC - Clarifies wine, beer, and juice samples ahead of HPLC testing for organic acids, sugars, and preservatives.
• Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
• Culture Vessel Filling - Equalizes pressure in sealed culture vessels by venting displaced air, keeping fill and drain lines fully closed.
