Grade B Glass Fiber Filter Paper 1.0um, 47mm, Nonsterile, 50/Pk SKU: EF19025

Glass Fiber (GF) Filter Paper - EF19025

Water quality monitoring programs need glass microfiber filters with documented retention specifications that satisfy regulatory method requirements. Thick fiber matrix provides high dirt-holding capacity that extends filter service life when processing turbid or heavily particulate samples. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. Under these conditions, chemical inertness across the full pH range means this filter handles the same aggressive sample matrices your analytical membranes process. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
