Grade A Glass Fiber Filter Paper 1.6um, 110mm, Nonsterile, 25/Pk SKU: EF19001

Glass Fiber (GF) Filter Paper - EF19001

Laboratories running both water quality and biological sample preparation benefit from glass microfiber grades that serve multiple analytical workflows. Thermal stability exceeding 500 degrees C allows direct ignition of the loaded filter for gravimetric suspended solids determinations. Working in concert, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Manufactured to a basis weight of 53g/m², each filter delivers the documented mass consistency that gravimetric methods require.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. With this in mind, chemical inertness across the full pH range means this filter handles the same aggressive sample matrices your analytical membranes process. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
