Grade B Glass Fiber Filter Paper 1.0um, 42.5mm, Nonsterile, 50/Pk SKU: EF19026

Glass Fiber (GF) Filter Paper - EF19026

Gravimetric analysis of suspended solids requires a thermally stable filter that survives ignition without contributing measurable residue to the determination. Chemically inert borosilicate glass resists degradation across the full pH range, maintaining fiber integrity through acid and alkaline sample matrices. Together, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

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.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
