Glass Fiber Filter Discs, 1.0um, 47mm, Binder Free, Nonsterile, 100/Pk
GVS SKU: FP047DAM10GLFC01

Featuring a binder-free borosilicate glass fiber depth medium, these 47 mm filter discs deliver 1.0 um nominal particle retention with a 0.45 mm media thickness, making them well suited for air monitoring and gravimetric work. The hydrophilic depth structure captures fine particulates throughout the matrix rather than at a single surface, providing high loading capacity and fast flow. Supplied nonsterile in packs of 100.

Key Glass Fiber Media Characteristics

• Binder free construction avoids binder extractables, supporting clean solvent filtration and accurate gravimetric determinations.
• Hydrophilic depth medium wets readily and retains particulates throughout the borosilicate matrix.
• 1.0 um nominal retention traps fine particles while maintaining low filter resistance and high flow.
• High particulate loading capacity handles heavily loaded air and aqueous samples and protects downstream membranes when used as a prefilter.
• Borosilicate glass fiber is biologically inert and highly resistant to oxidizing agents and weak acids.

Key Construction Characteristics

• Diameter: 47 mm circular disc format.
• Media thickness: 0.45 mm.
• Sterility: nonsterile.
• Pack: 100 discs per box.

The depth filtration structure maintains consistent retention across each disc, delivering reliable performance for repeatable analytical results. The binder-free borosilicate medium preserves sample integrity by minimizing extractable contamination during filtration and weighing.
