Description
Cytivas Whatman™ high-purity QM-B quartz fiber filters are designed for use in specific air monitoring applications. QM-B filters are similar to Cytivas standard QM-A quartz fiber filters, which are recommended more commonly for air testing applications. By comparison, QM-B is approximately twice as heavy, twice as thick, and offers slower flow rates. Because of these characteristics, QM-B can be used in air monitoring applications requiring increased strength or durability.
