Glass Fiber (GF) Filter Paper - EF19031
Laboratories running both water quality and biological sample preparation benefit from glass microfiber grades that serve multiple analytical workflows. Thick fiber matrix provides high dirt-holding capacity that extends filter service life when processing turbid or heavily particulate samples. In combination, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.
Key Filter Paper Characteristics
- Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.
- Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
- Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.
- Nominal retention of 1.2um provides the particle size cutoff appropriate for the analytical or preparative separation method.
- Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. For this application, chemical inertness across the full pH range means this filter handles the same aggressive sample matrices your analytical membranes process. 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.
