Grade 52 Filter for Quantitative Analysis, General, Circle

Description

Manufactured from high-quality cotton linters and treated to remove trace metals
High wet-strength and chemical resistance
Nominal particle retention of 7 µm
Medium flow rate (Herzberg filtration speed 235 s)
High purity (0.015% ash maximum)
Compatible with Hirsch or Büchner funnel applications

GE Healthcare’s Life Sciences 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. GE’s Grade 52 hardened filter paper is acid-treated to prevent fiber shredding during vacuum filtration or precipitate collection.
