Whatman^® quantitative filter paper, hardened low-ash, Grade 52

Cytiva′s Whatman Grade 52 is a general-purpose filter paper for quantitative analysis in Büchner funnel and other vacuum filtrations. The acid-hardened surface and low ash content enable efficient precipitate recovery. Cytiva′s business offers three grades of hardened low ash filter paper. All three are designed for use in Hirsch and Büchner funnel applications and can be customized for an exact fit.

Büchner funnel vacuum filtration

The quality of analysis resulting from vacuum filtration using a Hirsch or Büchner funnel relies on using a high-quality filter that avoids introducing artifacts into measurement. Cytiva′s Grade 52 hardened filter paper is acid-treated to prevent fiber shredding during vacuum filtration or precipitate collection.

Global SIAL customers (excluding Japan) can now order any product from the Cytiva Life Sciences consumables portfolio (prepack only) using GE′s product numbering system.

The legacy GE Whatman products that use the SIAL "Z" product numbering system will be discontinued and directly replaced with a product number using a "WHA" prefix plus the GE product code. For reference, the legacy "Z" product number is identified as a synonym on the "WHA" product number listing.
