Supplier's note

  1. Technical Breakthroughs:

    • Ultra-low ash content (Pro Model) reduces contamination risks by 47% compared to industry baselines.
    • Optimized pore structure improves filtration speed by 20% over traditional papers.
    • Triple chemical resistance (Pro Model) enables safe use with aggressive solvents.

  2. Version Selection Guide:

    • Base Model: Suitable for standard labs handling mild chemicals (e.g., basic pH solutions).
    • Advanced Model: Ideal for research requiring fine particle separation (e.g., nanomaterial analysis).
    • Pro Model: Best for harsh environments (e.g., handling concentrated acids/bases) or trace analysis requiring minimal residue.

With the Pro Model’s triple-industry chemical resistance, you can safely process aggressive reagents while maintaining precision. Pair its ultra-low ash content with high-purity assays to eliminate contamination—a game-changer for pharmaceutical or environmental testing labs.
