Quartzmicrofiber filters Grade QM-A from Whatman achieve fast filtration and have a high loading capacity. Manufactured without chemical binders from high-purity SiO₂ microfibers. Filtration speeds generally much higher than conventional cellulose paper filters. Efficient separation of micron and sub-micron sized particles. Ideal for use in flat, perforated Büchner funnels.
Recommended usage:
- Air sampling in acidic gases, stacks, flues.
- Aerosol testing.
- PM2.5/PM10-testing.
- Heavy metal analysis.
- Suitable for low-suction filtration.
- Usable up to 800 °C.
