Grade A Glass Fiber Filter Paper 1.6um, 47mm, Nonsterile, 100/Pk SKU: EF19010

Glass Fiber (GF) Filter Paper - EF19010

Gravimetric analysis of suspended solids requires a thermally stable filter that survives ignition without contributing measurable residue to the determination. High void volume between randomly packed glass fibers sustains rapid flow rates even as particulate loading accumulates during filtration. 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.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. With these demands in mind, grade-specific retention ratings let you match particle capture to the specific requirements of each analytical method in your laboratory. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
