Grade C Glass Fiber Filter Paper 1.2um, 293mm, Nonsterile, 10/Pk SKU: EF19051

Glass Fiber (GF) Filter Paper - EF19051

Air particulate sampling for gravimetric mass determination demands a filter medium with low tare weight variability and thermal stability through weighing procedures. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Because of this, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. 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.
