A standard grade filter paper for fine precipitates.
  • Increased filter surface area increases total loading capacity and decreases overall filtration time.
  • Reduced contact between filter and funnel maintains flow rate.
  • Eliminated need to quadrant-fold filter circles to fit conical funnels saves time in repetitive or multiple analyses.
  • Prepleated filters have the same technical properties as the respective filter circles.
  • Cellulose filters are used in qualitative analytical techniques to determine and identify materials.
  • Prepleated qualitative filters give improved flow rate and increased loading capacity compared to equivalent quadrant folded filters.
