Grade A Glass Fiber Filter Paper 1.6um, 70mm, Nonsterile, 25/Pk SKU: EF19013

Glass Fiber (GF) Filter Paper - EF19013

High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. High void volume between randomly packed glass fibers sustains rapid flow rates even as particulate loading accumulates during filtration. On this basis, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Addressing this directly, ultra-low blank values from pure borosilicate glass protect the accuracy of your trace-level environmental and gravimetric determinations. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
