Details
This Whatman,1440-240, Grade 40 filter paper has a diameter of 240 mm and comes in a pack of 100.
Grade 40: The classic general purpose ashless filter paper with medium speed and retention. Typical applications include gravimetric analysis for numerous components in cements, clays, iron and steel products; as a primary filter for separating solid matter from aqueous extracts in general soil analysis, quantitative determination of sediments in milk and as a pure analytical grade clean-up filter for solutions prior to AA spectrometry. Used also as a high-purity filter in the collection of trace elements and radionuclides from the atmosphere.
Whatman Grade 40 high-purity filters from Cytiva's business are general-purpose papers for quantitative analysis. Grade 40 filters are suitable for a variety of analytical filtration applications.
Features:
High-purity filters contain 0.007% maximum ash content
Medium nominal particle retention rating of 8 µm
Medium filtration speed (Herzberg 340 s)
Particularly useful for gravimetric analysis
