Filters without binder withstand up to 932°F (500°C); filters with binder withstand up to 250°F (120°C). Grades GC90, GS25, and DP70 with binder offer higher wet strength and lower fiber release. Quartz fiber filters have very low trace metal content and can withstand up to 1832°F (1000°C). Choose quartz fiber filters to sample acidic gases at high temperatures or for air pollution analysis.
Since quartz fiber is expensive, it has limited appliions. It is used mainly for producing composite materials (due to having higher stability compared to glass fiber) and in electrical appliions where thermal resistance and dielectric properties are important. It can be used in filtration appliions where alternatives such as glass fiber filters cannot be used.
Microquartz filters are useful for testing hot stack gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, microquartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of ...
Quartz fiber filter, grade QR100, 25mm Ø, 85g/m², thick. No binder, max. temp. 1000 °C. Excellent chemical resistance, biologically inert. Air pollution analysis; sample acidic gases at .
Highpurity quartz microfibre filters are mainly used for the low particle content in air pollution monitoring especially when a very pure filter is required or when the physical or chemical conditions of the gases are extreme. Our quartz fibres have excellent filtration properties and outstanding weight and dimension stability. They can be used for air sampling and gravimetric calculations ...
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 ...

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. Because of the low .
TFAQS810 Slotted Quartz Fiber Filters (25 per box) GLASS FIBER FILTER DATA. Glass Fiber Filters are especially recommended wherever gravimetric weighing analysis may be required because of their nonhygroscopic properties, they will maintain constant weight under wideranging conditions of ambient humidity. Their excellent loading characteristics make them ideal for routine air monitoring ...
