Details
This Whatman,1441-125, Grade 41 filter paper has a diameter of 125 mm and comes in a pack of 100.
Grade 41: The fastest ashless filter paper, recommended for analytical procedures involving coarse particles or gelatinous precipitates (e.g. iron or aluminum hydroxides). Also used in quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates.
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.
Features:
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
