Glass Microfiber Filter Paper - 1510-3200 - Grade 151, 32cm 2.10cm Grade 141 is particularly recommended

Grade 141 is particularly recommended for pre-filtration of membrane filters and is also used in combination with Grade 121 as a highly efficient protective and retentive grade density pre-filter for membrane filters

as this media will withstand higher temperatures

Ahlstrom-Munksjö Grade 237 is also suited for electrophoresis and the separation of inorganic compounds

For microwave technology systems

This high absorbency grade is twice as thick as Grade 642 with similar particle retention

Glass Microfiber Filter Paper - 1510-3200 - Grade 151, 32cm 2.10cm Grade 141 is particularly recommendedAhlstrom Munksj 151 0. 7 m, Slow Speed This high performance grade is designed to retain extremely fine particles down to 0. 7 m. Grade 151 has retention comparable to membrane filter while providing high flow and loading capacity. Grade 151 is recommended for filtering fine precipitated proteins. In the filtration of nucleic acids and difficult biochemical solutions, Grade 151 is used in combination with Grade 141 as a highly efficient protective and
