	AQFA03700	Quartz Fiber Membrane Filter without binder	116	Add to Cart
Background Information OverviewMillipore 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. Catalogue Number AQFA03700 Chemistry Quartz Fiber Contaminant of Interest Elemental Carbon (Diesel Particulate) Filter Code AQFA Filter Color White Filter Diameter (⌀) 37 mm Filter Surface Plain Filter Type Depth filter Flow Rate 1.6 mL/min x cm² Material Size 100 pack, AQFA, 37 mm Maximum Operating Temperature 950 °C Pore Size Not Applicable Regulated Test Method Number NIOSH 5040 Thickness 430 µm Wettability Hydrophilic
