Grade B Glass Fiber Filter Paper 1.0um, 50mm, Nonsterile, 50/Pk SKU: EF19027

Glass Fiber (GF) Filter Paper - EF19027

Gravimetric analysis of suspended solids requires a thermally stable filter that survives ignition without contributing measurable residue to the determination. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

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.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Depth filtration architecture gives you the particle loading capacity to process turbid samples that would blind cellulose papers or surface-capture membranes. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
