Grade D Glass Fiber Filter Paper 2.7 um, 8 Inch x 10 Inch, Nonsterile, 25/Pk SKU: EF19068

Glass Fiber (GF) Filter Paper - EF19068

Water quality monitoring programs need glass microfiber filters with documented retention specifications that satisfy regulatory method requirements. Hydrophilic glass surface wets immediately on contact with aqueous solutions, requiring no pre-conditioning before filtration begins. Each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Manufactured to a basis weight of 121g/m², each filter delivers the documented mass consistency that gravimetric methods require.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. Meeting this challenge, ultra-low blank values from pure borosilicate glass protect the accuracy of your trace-level environmental and gravimetric determinations. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
