Grade F Glass Fiber Filter Paper, 0.7um, 90mm, Nonsterile, 25 Pk SKU: EF19067

Glass Fiber (GF) Filter Paper - EF19067

Processing samples with high suspended solids concentrations requires a filter medium engineered for particle loading capacity, not just surface retention. Hydrophilic glass surface wets immediately on contact with aqueous solutions, requiring no pre-conditioning before filtration begins. By design, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Manufactured to a basis weight of 75g/m², each filter delivers the documented mass consistency that gravimetric methods require.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. For exactly this reason, multiple retention grades from 0.7 to 2.7 micrometers let you select the particle capture threshold each of your methods specifies. 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.
