Learn About Qualitative Filter Papers

Manufactured from the same raw materials as the ashless grades, the qualitative filter paper is suited for ordinary filtration when we need to determine materials by using qualitative analytical techniques in the lab, with the features of fast flow rate due to their structure.

Qualitative filter paper has different designs. The standard qualitative filter papers with high purity are perfect for qualitative analyses where a low ash content are required. And the wet strengthened qualitative filter papers are basically used for analytical and routine analyses when no gravimetric analyses are required. We also can them for pressure or vacuum filtration.

The qualitative filter paper is available for a wide range of applications. Hawach Scientific high-quality filter paper is in Low ash content (<0.1%). Nominal retention of our products can vary from 2.5um to 20um. Filtration speed is affected by these specifications and ranges from very slow to very fast.

When choosing qualitative filter paper, you may consider about particle retention and nominal pore size required, wet strength level needed, and the diameter as well.
