Grade D Glass Fiber Filter Paper 2.7 um, 110mm, Nonsterile, 10/Pk SKU: EF19046

Glass Fiber (GF) Filter Paper - EF19046

Water quality monitoring programs need glass microfiber filters with documented retention specifications that satisfy regulatory method requirements. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Particle retention rating of 2.7um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• 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.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. Under these conditions, 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.

• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Protein Precipitation - Captures precipitated proteins from biological fluids for downstream immunoassay and biochemical characterization.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
