Glass Fiber (GF) Filter Paper - EF19057
High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. As designed, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.
Key Filter Paper Characteristics
- Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
- High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
- Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
- Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
- Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. Rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
