PALL AP-4528 Acrodisc PSF Syringe Filters with Nylon Membrane - GxF/0.45 µm (1000/pkg)

Product Overview:
The PALL AP-4528 Acrodisc PSF Syringe Filters with Nylon Membrane deliver exceptional sample filtration performance for demanding analytical chemistry applications. Engineered with a robust GxF multi-layer glass fiber prefilter and a premium 0.45 µm nylon membrane, these filters ensure clarity and consistency when preparing samples for High-Performance Liquid Chromatography (HPLC) or similar laboratory analysis. With a larger throughput and optimized chemical compatibility, this syringe filter solution shields your valuable instrumentation while maximizing your lab’s productivity.

Main Advantages:

  • Superior Throughput: Advanced GxF glass fiber prefilter technology provides two to four times more throughput than conventional syringe filters, allowing for efficient sample processing without frequent filter changes.
  • Extended Instrument & Column Life: The 0.45 µm pore size effectively removes particulates from samples, defending sensitive instrument components and chromatography columns against damaging blockages and reducing system downtime.
  • Unmatched Chemical Compatibility: The nylon membrane is highly compatible with both aqueous and solvent-based samples, including esters, bases, and alcohols, making it a versatile choice for diverse laboratory tasks.

Why This Product is Essential:
Reliable sample preparation is the cornerstone of successful analytical results. These PALL AP-4528 Acrodisc PSF Syringe Filters are essential for any laboratory aiming to protect its instrumentation, decrease maintenance interruptions, and ensure accurate, reproducible data. Investing in high-quality syringe filters minimizes costly repairs and consistently safeguards your lab’s critical processes.
