Description:

Cytiva Whatman 1440-150 Grade 40 Quantitative Ashless Filter Paper, 15cm. Whatman Grade 40 high-purity filters are general-purpose papers for quantitative analysis. Grade 40 filters are suitable for a variety of analytical filtration applications. High-purity filters support accurate analysis in applications sensitive to very low levels of background contamination and in gravimetric analysis where ash content might affect weight measurements of combusted samples. 100/box.

  • 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

Grade 40 ashless paper is suited to:

  • Soil analysis, when separating solid matter from aqueous extracts
  • Quantitative determination of milk sediment
  • Use as a clean-up filter for solutions prior to atomic absorption (AA) spectrometry
  • Analysis of constituent components in cements, clays, iron, and steel products
  • Collection of trace elements and radionuclides from the atmosphere
