Thumbnail Filmstrip of Grade HT Quartz A Microfiber, 2.2µm, 45mm, Binderless SiO2, High-Temp Air Monitoring, 100/Pk Images
- Binderless quartz construction eliminates organic contamination and maintains purity at extreme temperatures
- 99.999% high purity SiO2 with ultra-low metals delivers contamination-free results for critical trace analysis
- Exceptional thermal stability withstands continuous operation to 1150°C without degradation or dimensional change
- 2.2µm retention efficiency captures fine particulates while optimizing airflow in high-volume sampling applications
- Hydrophobic surface chemistry resists moisture interference during ambient air and stack gas monitoring
- Fine porosity microfiber matrix achieves 99.999% efficiency for 2.20µm particles in air filtration protocols
- Robust tensile strength of 285g/15mm (ASTM D828) ensures handling integrity during filter installation and changeout
- Minimal loss on ignition below 2% validates chemical purity for gravimetric analysis and elemental determinations
- Standard 45mm diameter accommodates high-volume sampling equipment and universal filter holder configurations
- Autoclavable glass construction enables pre-cleaning protocols for ultra-trace metal analysis applications
