Millipore® Quartz Fiber Membrane Filter without Binder, 8 in. x 10 in., Hydrophilic, Merck KGaA (CAT#: STEM-L-4084-LKN)

Filter Code: AQFA.
Filter Type: Depth filter.

Millipore® Quartz Fiber Filters (Type AQFA) are made of quartz fibers with no glass fibers or binders. Unlike glass fiber filters, Millipore's pure quartz manufacturing process involves a heat treatment step to improve the composition and prevent the filters from reacting with acidic gases. This makes quartz filters ideal for measuring heavy metal concentrations and small amounts of particles (such as the US EPA PM 10 ambient air monitoring method). Quartz filters also have good weight and form stability.
