Whatman® Grade 3 Qualitative Filter Paper

Whatman® Grade 3 filter paper is double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging. The extra thickness gives increased wet strength and makes this grade highly suitable for use in Buchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier.

Whatman® Grade 3 filter paper has particle retention of 6 μm at 98% efficiency.
