Grade D Glass Fiber Filter Paper 2.7 um, 47mm, Nonsterile, 50/Pk SKU: EF19056

Glass Fiber (GF) Filter Paper - EF19056

High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. Thick fiber matrix provides high dirt-holding capacity that extends filter service life when processing turbid or heavily particulate samples. Consequently, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Nominal basis weight of 121g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.

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