Grade A Glass Fiber Filter Paper 1.6um, 37mm, Nonsterile, 100/Pk SKU: EF19006

Glass Fiber (GF) Filter Paper - EF19006

Processing samples with high suspended solids concentrations requires a filter medium engineered for particle loading capacity, not just surface retention. Thermal stability exceeding 500 degrees C allows direct ignition of the loaded filter for gravimetric suspended solids determinations. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

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.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.

When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. Thermal stability exceeding 500 degrees C supports the ignition step your gravimetric method requires without introducing filter decomposition artifacts. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
