Glass Fiber (GF) Filter Paper - EF19066
Vacuum filtration of turbid environmental samples requires a depth filter that maintains flow rates through heavy particulate loads without premature blinding. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.
Key Filter Paper Characteristics
- Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
- Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
- Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
- Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
- Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. For this purpose, rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
