Frequently asked questions
Should I choose a glass microfiber filter or quartz filter?
The choice between glass microfiber and quartz filters depends on your application:
- Choose quartz filters for high-temperature testing and trace-level analysis. They withstand up to 1200°C and offer low background contamination.
- Choose glass microfiber filters for general particulate capture in air or liquid, especially when working below 500°C and when you need finer retention (0.3–1.2 µm).
What particle size retention are offered?
Glass microfiber filters typically offer particle size retention ranging from 0.3 µm to 1.2 µm, depending on the grade. They are suitable for fine particulate capture in air and liquid filtration applications.
Are quartz filters suitable for high-temperature testing?
Quartz fiber filter can be used at temperatures ranging from 800°C to 1200°C.
Can glass microfiber filters be used for environmental testing?
Yes, glass microfiber filters are widely used in environmental testing, especially for air sampling of particulate matter (PM10, PM2.5), due to their fine particle retention, high loading capacity, and thermal stability up to ~500°C.
What sizes and formats are available?
Cytiva offers a range of glass microfiber filters in various sizes and formats tailored to different applications.
Available in discs (common diameters include 47, 90, 142, up to 185 mm), sheets, RTU (ready to use), and in different grades such as GF/A, GF/B, GF/C™, GF/F filters.
