Grade A Glass Fiber Filter Paper 1.6um, 8 Inch x 10 Inch, Nonsterile, 25/Pk (same as TE-G653) SKU: EF19000

Glass Fiber (GF) Filter Paper - EF19000

Air particulate sampling for gravimetric mass determination demands a filter medium with low tare weight variability and thermal stability through weighing procedures. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. In sum, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
• 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.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. To address this, thermal stability exceeding 500 degrees C supports the ignition step your gravimetric method requires without introducing filter decomposition artifacts. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
