Membrane filters typically have absolute pore size ratings <1µm, with some exceptions. Because of their very fine pore structure, membrane filters tend to trap the majority of particles on the surface. However, smaller particles with diameters near or below the pore size rating can be captured within the membrane or pass through the membrane.
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.
Quartz Microfiber Filters are used for air sampling in acidic gases (except HF), stacks, flues, and aerosols, particularly at high temperatures and in PM-10 testing as well as where absolute purity of the filter medium is required. Quartz Microfiber Filters also exhibit good weight and form stability. Features
MF-Millipore™ mixed cellulose esters (MCE) membrane filter discs, produced from biologically inert cellulose acetate and cellulose nitrate, are a versatile choice for biological, analytical, and environmental monitoring as well as research applications. With a consistent thickness, uniform pore structure, and smoother surface than pure nitrocellulose membranes, hydrophilic MF-Millipore™ membranes are available in a variety of pore sizes, colors, surfaces, and diameters.
The RO membrane filter can only achieve 2/3 of total line pressure. A Water Purifier Fitted With A RO Membrane Filter. Do RO Membrane Filters Remove Important Minerals? Yes, the RO membrane filters remove nearly 97% of the total mineral content in the water. However, this should not be cause for any alarm.
Price:$104.60. About Quartz A Glass Fiber. Cross Reference. Specifications. Zefon Quartz A filters are made of binderless quartz microfiber and feature fine porosity with a 99.999% efficiency in air filtration for the retention of 0.6μm particles in air at a flow rate of 5cm/ second. Primarily used in air pollution monitoring, atomic
Choose a filter or membrane based on: 1) Chemical compatibility of the membrane and housing with your sample matrix. 2) Size and amount of particulates in the sample. 3) Potential interactions (binding) between the membrane and sample components. 4) Special considerations such as requirement for prefilter or inorganic ion certification.

QM-A quartz microfiber filters from Cytiva come in a wide range of circle diameters, as well as 25-piece sheets. QM-A sheets (1851-8866) are sequentially numbered according to U.S. Environmental Protection Agency (EPA) standards and are suitable for most applications. Looking for a filter paper, membrane filter, or syringe filter?
Product Description. Quartz fiber filters are made of very pure quartz fibers with no binders and glass fibers. The pure quartz composition prevents 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.
These filters are made of glass fiber and contain no resin binders that could contaminate your analysis. If you are testing for volatiles your filter holder will usually take a 90mm diameter filter (Catalog # AP4009000). If you are testing for non-volatiles, semi-volatiles or metals your filter holder will usually take a 142mm diameter filter
