Glass Fiber Filter Discs, 1.6um, 47mm, Nonsterile, 100/Pk
GVS SKU: FP047DAM64GLFC01

Featuring a borosilicate glass fiber depth medium bonded with a binder, these 47mm filter discs deliver fine particle retention down to a nominal 1.6um while maintaining the fast flow and high loading capacity that gravimetric and air monitoring work demand. The depth structure traps particulate throughout the media rather than at a single surface plane, providing outstanding dirt-holding capacity with low filter resistance. Each disc carries a nominal basis weight of 64 g/m2 and a thickness of approximately 270um, and the media is naturally hydrophilic for rapid aqueous wetting.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass fiber medium wets quickly with aqueous samples and requires no prewetting.
• Nominal 1.6um particle retention captures fine particulates while preserving fast flow rates suited to high-throughput filtration.
• Depth filtration structure distributes captured particles throughout the media, supporting high particulate loading before clogging.
• Binder-bonded matrix reduces media migration and adds the mechanical strength needed for high-volume aqueous filtrations.
• Broad chemical compatibility with resistance to weak acids and oxidizing agents, and the medium is biologically inert.

Key Construction Characteristics

• Diameter: 47mm circular disc format.
• Nominal basis weight: 64 g/m2.
• Nominal thickness: approximately 270um (0.27mm).
• Sterility: nonsterile.
• Pack: 100 discs per box.

These discs provide consistent, reproducible retention across high particulate loads, making them dependable for air pollution sampling and gravimetric determinations. The strong, low-migration media helps protect downstream membranes and preserves sample integrity during demanding filtration runs.

• Air Pollution Monitoring Captures airborne particulate for gravimetric and atmospheric pollution measurement using the hydrophilic glass fiber medium.
• Gravimetric Analysis Provides a stable, low-migration depth medium for particulate weight determinations.
• Prefiltration Protects and extends the life of downstream membrane filters by trapping coarse and fine particulates upstream.
• Suspended Solids Analysis Retains fine particulates from water and wastewater samples for solids quantification.
• Sample Clarification Delivers low cost clarification of heavily loaded aqueous samples ahead of analysis.
• Environmental Sample Prep Handles high particulate loads typical of environmental water and air samples without rapid clogging.
