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.
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.
