Glass Fiber (GF) Filter Paper - EF19078
Liquid scintillation counting and radioimmunoassay procedures need a binderless glass fiber substrate that introduces no chemical interference to sensitive detection methods. Grade-specific fiber diameter and packing density produce defined retention ratings that remain consistent across manufacturing lots. As designed, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.
Key Filter Paper Characteristics
- Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
- Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
- Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
- Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
- High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Under these conditions, rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. 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.
