Grade 41

Whatman Grade 41 environmental pollution papers are designed for fast filtration and are among the quickest in the Whatman ashless range. These papers are specifically tailored for quantitative analysis in environmental studies, making them ideal for tasks involving soil and air pollution analysis.

Key Features:

Extremely Low Ash Content: With a maximum ash content of 0.007%, these papers minimize contamination, which is crucial for accurate quantitative analysis.
Nominal Particle Retention: They offer a 20 µm particle retention rating, allowing for the filtration of larger particles commonly encountered in environmental samples.
Fast Filtration Speed: The Herzberg filtration speed is 54 seconds, making them one of the fastest in the ashless range. This speed is particularly beneficial when time-efficient filtration is required.
Applications: Grade 41 filters are commonly used in routine air pollution analysis, where rapid filtration of particulates from air samples is needed. As well as in soil pollution analysis, where the quick separation of particles from soil extracts is crucial.
These filters are well-suited for environmental pollution studies, providing both speed and accuracy in quantitative analysis.
