Grade B Glass Fiber Filter Paper 1.0um, 142mm, Nonsterile, 10/Pk SKU: EF19018

Glass Fiber (GF) Filter Paper - EF19018

Laboratories running both water quality and biological sample preparation benefit from glass microfiber grades that serve multiple analytical workflows. Hydrophilic glass surface wets immediately on contact with aqueous solutions, requiring no pre-conditioning before filtration begins. In practice, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Nominal basis weight of 143g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. 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.

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