Product Description

Whatman Grade 41 ashless filter paper,460 × 570 mm sheet (100/pkt)
Cytiva's Whatman™ Grade 41 environmental pollution papers are among the fastest filter papers in the Whatman™ ashless range. This gravimetric filter is well suited for quantitative analysis of soil and air.
• Extremely low ash content (0.007% ash maximum)
• 20 µm nominal particle retention rating
• Fast filtration speed (Herzberg 54 s)
• Commonly used for routine air pollution analysis and soil pollution analysis
Grade 41 filters are also commonly used in preparing solid environmental samples (e.g., soils, sludges) for metals analysis after nitric acid digestion. They are available in a convenient, disposable, 47 mm filter funnel with a 250 ml capacity. The 47 mm diameter filter can be easily removed for further analysis or culturing.
Whatman™ quantitative paper comes in a variety of particle retenctions, 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.
