Specs.
Retention in um: 2.0 Filtration Speed Herzberg Sec 100mls: 229 Filtration Speed Rapidity mls/min: 30 Load Capacity: Medium Cross Referance: 40
Ashless Grades (Ash 0.007%)
These standard ashless grades are high purity filter papers suitable forroutine quantitative gravimetric techniques and in the preparation ofsamples for use in analysis involving instrumental techniques.
Ahlstrom 74: 2.0μm – Medium Speed
This grade has medium flow rate andgood particle retention and is the mostcommonly used acid-washed filter.Ahlstrom 74 covers a wide range ofgeneral ashless filtration applications.It is used for gravimetric analysis ofnumerous components (e.g.: cements,copper, clay, bismuth, silicon, iron)found in heavy industries such asconstruction, mining or steel. Ahlstrom74 is also used as a high purity filter forspeedy filtering of trace elements suchas silver chromate, lead sulfate, zincand ammonium hydroxides. Ahlstrom 74is also found in general soil analysis forseparating solid from aqueous extracts.
