Product Description
Filter paper Grade: 41, 70 mm
  • Extremely low ash content (0.007% ash maximum)
  • 20 micro-m nominal particle retention rating
  • Fast filtration speed (Herzberg 54 s)
  • Commonly used for routine air pollution analysis and soil pollution analysis

Aside from Grade 41 environmental pollution papers, Whatman quantitative paper comes in a variety of particle retentions, filtration speeds, and filter thicknesses to provide you with the appropriate filter for your precipitate. Also, see our hardened ashless grades for analysis requiring the use of strong acids or bases.

Fast ashless paper for pollution analysis

Whatman Grade 41 filters from GE Healthcares Life Sciences business are suitable for quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates.

Grade 41 filters are also commonly used in preparing solid environmental samples (e.g., soils, sludges) for metals analysis after nitric acid digestion.
