Grade F Glass Fiber Filter Paper, 0.7um, 293mm, Nonsterile, 10 Pk SKU: EF19079

Glass Fiber (GF) Filter Paper - EF19079

Air particulate sampling for gravimetric mass determination demands a filter medium with low tare weight variability and thermal stability through weighing procedures. High void volume between randomly packed glass fibers sustains rapid flow rates even as particulate loading accumulates during filtration. Altogether, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Rated at 0.7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• High void volume between randomly packed fibers sustains rapid flow rates even as accumulated particulate loading increases during filtration.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Under these conditions, high void volume within the fiber matrix extends the sample volume you can process before flow restriction requires a filter change. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
