Recommended filters for controlling both air and water pollution. Made of borosilie glass fibres without binders. Glass fibre filters absorb the finest particles down to 1 μm from liquids, in air, gases and even aerosols with – μm are separated. The large surface area (about 2m²/g) provides an outstanding retention capacity.

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.

Quartz fiber filters have very low trace metal content and can withstand temperatures up to 1832°F (1000°C). Use to sample acidic gases at high temperatures or for air pollution analysis. The QR100 Grade filters offer superior chemical resistance and will not absorb acidic gases. MORE + LESS . / Pkg of 100.

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 ...

Vibration resistant (low impact noise) for Block Up Down converters. development and production in Switzerland. quality, reliability, flexibility, customerspecific tailoring. small package sizes ( mm, 7x5 mm, 14x9 mm) high frequency stability (± ppm from 40 to +85°C) .

Ahlstrom's 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 ...

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 ultra 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 leve of alkaline earth ...
