  • High wet-strength and chemical resistance
  • Nominal particle retention of 7 µm
  • Medium flow rate (Herzberg filtration speed 235 s)
  • High purity (0.015% ash maximum)
  • Compatible with Hirsch or Büchner funnel applications

Büchner funnel vacuum filtration

The quality of analysis resulting from vacuum filtration using a Hirsch or Büchner funnel relies on using a high-quality filter that avoids introducing artifacts into measurement. Cytiva's Grade 52 hardened filter paper is acid-treated to prevent fiber shredding during vacuum filtration or precipitate collection.
