General Use Filter Papers

Recommended for identification of substances, clarification of liquids and for the preparation of samples in a broad range of chemical analysis.

  • Made of super-refined cellulose
  • For quick separation of large particles
  • For reliable clarification of viscous liquids
  • Three surfaces available: smooth, grained and creped
  • Creped filter papers have a particularly large surface area and correspondingly shorter filtration times
  • Available as plain and folded discs, sheets, cuts and rolls

 

These filters are available as filter circles and folded filters with the following sizes (in mm):

47 – 55 – 70 – 90 – 110 – 125 – 150 – 185 – 240 – 320 (folded filters from 70 mm).

Other sizes, sheets, rolls and special cuts are available on request.
