Grade C Glass Fiber Filter Paper 1.2um, 25mm, Nonsterile, 100/Pk SKU: EF19037

Glass Fiber (GF) Filter Paper - EF19037

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. In sum, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Particle retention rating of 1.2um defines the separation threshold for the application, determining which solids are captured and which pass through.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. In particular, binderless borosilicate construction eliminates the organic extractables that would compromise your downstream chromatographic or spectroscopic analysis. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
