Description

Description générale

Grade 1: 11 μm (medium flow filter paper)

The most widely used filter paper for routine applications with medium retention and flow rate. 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.
