Quantitative filter papers, hardened low ash grades, grade 50, Whatman™
Filtry Papíry filtrační Papír kvantitativní filtrační
These highly glazed filter papers made from high quality cotton linters support vacuum filtration in Büchner funnels or Hirsch funnels and enable strong retention of very fine crystalline precipitates.

  • Thinner filter design than most Büchner filter papers
  • Acid treated for high wet strength and chemical resistance
  • Withstand wet handling and precipitate removal by scraping
  • Alpha cellulose content ≥98%

For many vacuum filtration applications, a thin filter paper with a slow flow rate and excellent wet strength can maintain sample quality and purity. Because these filter papers are hardened to minimize fibre shredding, they are a good choice for use as carriers in integrated circuits.

* Also available in smear tab format for wipe testing (e.g., testing of surfaces for radionuclide contamination).
