Filter Paper, No.3 Qualitative, General Application
Details
General description
These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters. The Pore Size is 6um, 185 mm diameter, 196 thickness, and basic weight 185 g/m2
Grade 3: 6 μm, (medium flow, thick filter paper)
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 Büchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier.
