	AQFA8X105	Quartz Fiber Membrane Filter without binder	936	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 AQFA8X105 Chemistry Quartz Fiber Filter Code AQFA Filter Color White Filter Diameter (⌀) Not Applicable Filter Surface Plain Filter Type Depth filter Flow Rate 1.6 mL/min x cm² Material Size 50 pack, AQFA, 8 x 10 in. Maximum Operating Temperature 950 °C Pore Size Not Applicable Thickness 430 µm Wettability Hydrophilic

	TETP01300	Isopore Membrane Filter	65	Add to Cart
Air Flow Rate 60 L/min x cm²/psi Background Information The Isopore™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore™ membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Matched-weight filters are not usually required because of low, constant tar and ash weights.Features & Benefits:•Membrane structure retains particles on the surface, simplifying counting and analysis •Isopore™ membranes do not stain, resulting in low background interference •Non-hygroscopic, allowing for rapid drying and reduced sample analysis time •Translucent material does not require clearing for transmitted light microscopy; also available in brown variety Applications:Air Monitoring, Epifluorescent Microscopy, Chemotaxis Assays Catalogue Number TETP01300 Chemistry Polycarbonate (PC) Diameter Biological Information Media Filter Code TETP Filter Color White Filter Diameter (⌀) 13 mm Filter Surface Plain Filter Type Screen filter Flow Rate 60 L/min x cm²/psi Gravimetric Extractables < 1% Material Size polycarbonate, Hydrophilic, 8.0 µm, 13 mm, white, plain, 100 Maximum Operating Temperature 140 °C (possible reduction in flow rates may occur after autoclaving) Media Isopore® Pore Size 8.0 µm Porosity % 5%–20% Thickness 18 µm Trade Name Isopore Wettability Hydrophilic
