Cytiva's Whatman™ Grade 3 Qualitative Filter Paper

Cytiva's Whatman™ grade 3 cellulose filter paper is used in qualitative analytical techniques to determine and identify materials. It has double the thickness of Grade 1 with still finer particle retention and excellent loading capacity. Thus more precipitate can be held without clogging. The extra thickness gives increased wet strength and makes this grade highly suitable for use with Buchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier. Retention: 6µm.
