PALL AP-4794 Acrodisc PSF Syringe Filters with PVDF Membrane - GxF/0.2 µm (1000/pkg)

Product Overview:
Increase the reliability and performance of your laboratory analyses with the PALL AP-4794 Acrodisc PSF Syringe Filters featuring an advanced PVDF membrane in a GxF configuration. Specifically engineered for analytical chemistry applications, these syringe filters excel at removing particulate contamination before sample injection. Their precise 0.2 µm pore size ensures your samples remain free of impurities, protecting your sensitive instrumentation and streamlining your workflow for consistent, high-quality results.

Main Advantages:

  • Superior Throughput: The integrated multi-layer glass fiber prefilter provides two to four times the throughput of standard syringe filters, meaning faster processing and fewer filter changes even with challenging samples.
  • Extended Instrument and Column Lifespan: By trapping contaminants before sample introduction, these filters protect both sensitive instrument parts and costly chromatography columns from particulate buildup and clogs.
  • Exceptional Chemical Compatibility: Thanks to the PVDF membrane, these filters handle aggressive acids and alcohols, providing flexibility across a wide range of sample types and solvents (excluding acetone, DMF, DMSO, or strong bases).

Why This Product is Essential:
For any lab performing precise chromatography or analytical testing, routine filtration is non-negotiable. The PALL AP-4794 Acrodisc PSF Syringe Filters deliver reliability, enhanced efficiency, and instrument protection, making them an indispensable tool for improving data accuracy while minimizing costly system downtime. For professionals seeking laboratory syringe filters with PVDF membranes, this product is the gold standard for clean, reproducible results.
