      DescriptionQuartz Fiber Membrane Filter without binder
      Background InformationOverview
      Millipore fibrous disc filters are available in a wide range of flow rates and throughput capacities.

      Quartz Fiber Filters (Type AQFA)
      Made of quartz fibers with no glass fibers or binders. Millipore's pure quartz manufacturing process involves a heat treatment step to improve the composition and prevent the filters from reacting with acidic gases, unlike glass fiber filters that can react and cause false readings. This makes quartz filters well suited for measuring heavy metal concentrations and small amounts of particles (such as the US EPA PM 10 ambient air monitoring method).

      The quartz filters also exhibit good weight and form stability.
