Filtry z włókna kwarcowego QM-B

Filtry z mikrowłókien kwarcowych o najwyższej czystości przeznaczone do określonych zastosowań w monitoringu powietrza.
High-purity Whatman QM-B quartz fiber filters from GE Healthcare’s Life Sciences business are designed for use in specific air monitoring applications.

QM-B filters are similar to GE’s 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.

The Whatman range of high-purity quartz filter options also includes Grade QM-A and Grade QM-H filters, which can withstand temperatures up to 800°C and 900°C, respectively. Each filter grade has unique strengths for air monitoring applications.
