Glass Fiber (GF) Filter Paper - EF19040
Gravimetric analysis of suspended solids requires a thermally stable filter that survives ignition without contributing measurable residue to the determination. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. Working in concert, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.
Key Filter Paper Characteristics
- Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
- Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
- High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
- Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
- Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Grade-specific retention ratings let you match particle capture to the specific requirements of each analytical method in your laboratory. 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.
