Quartz Fiber Filter Discs, 47mm, Binder-Free, Fast Flow, Nonsterile, 100/Pk
GVS SKU: FP047D0QF1QUFC01

Featuring a binder-free depth medium made from 100% pure quartz microfiber, these 47mm discs deliver high-purity particulate collection for demanding air and emissions sampling. The binderless construction provides a Retention DOP of 99.998% and a nominal media thickness of 440um, supporting fast flow and high particulate loading. With a nominal basis weight of 85 g/m2, the quartz medium withstands extreme temperatures and aggressive chemical exposure where standard glass microfiber would fail.

Key Glass Fiber Media Characteristics

• 100% pure quartz microfiber with zero binders for the highest purity sampling and minimal background interference
• Binder-free construction delivers a Retention DOP of 99.998% for efficient capture of fine airborne particulates
• Depth media structure provides high particulate loading capacity with fast air flow permeation
• Greater chemical resistance at high temperatures than glass microfiber, suited to acid gas environments
• Nominal media thickness of 440um and nominal basis weight of 85 g/m2 for consistent, reproducible sampling

Key Construction Characteristics

• Disc format, 47mm diameter, for standard filter holders and air sampling cassettes
• Hydrophilic quartz microfiber medium suited to gravimetric and chemical analysis
• Supplied nonsterile, 100 discs per box

These quartz fiber discs maintain sample integrity through high-temperature and chemically aggressive sampling conditions, providing reliable, reproducible particulate retention. The binder-free, high-purity medium minimizes analytical background, supporting accurate downstream measurement.
