Supplier's note

  1. Three Technical Breakthroughs:

    • Pro Model’s Ash Content: At 0.005%, it’s half the industry standard (0.01%), enabling ultra-trace analysis.
    • Advanced Porosity Control: Adjustable pore sizes (12–20 pores/cm²) optimize flow rates for diverse media.
    • Base Model’s Cost Efficiency: Meets ISO 605 standard at 0.015% ash, ideal for routine labs.

  2. Optimal Version Selection:

    • Base Model: Suitable for general labs requiring basic quantitative analysis (e.g., routine pH testing).
    • Advanced Model: Preferred for mid-tier research where faster filtration (15% boost) and lower ash (0.01%) are critical.
    • Pro Model: Best for high-stakes environments like pharmaceutical R&D, where tripled chemical resistance and minimal ash ensure contamination-free results.

*Performance gain vs. Base Model. **Meets ISO 605 and ASTM D281 specifications.
