Glass Fiber Filter Paper Discs, 1.5um Retention, 47mm, Binder Free, Nonsterile, 100/Pk
GVS SKU: FP047DFAAHGLFC01

Featuring a binder-free borosilicate glass microfiber depth medium, these 47mm filter discs deliver a 1.5um nominal particle retention with a thickness of 0.28mm. The depth structure provides a large surface area and outstanding impurity retention capacity combined with low filter resistance, making it well suited to heavily loaded aqueous samples. Because the medium contains no binder, it avoids binder extractables and supports clean analytical and gravimetric determinations.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic depth medium composed of 100% borosilicate glass fibers for fast wetting with water and aqueous solutions.
• 1.5um nominal particle retention traps fine particulates while maintaining high flow.
• High particulate loading capacity from the open depth structure, ideal for heavily loaded and turbid samples.
• Binder free construction avoids extractables, supporting gravimetric and analytical accuracy.
• Biologically inert and chemically robust, withstanding high temperatures and resisting oxidizing agents and weak acids.

Key Construction Characteristics

• Borosilicate glass fiber medium in a circular disc format measuring 47mm in diameter.
• 0.28mm media thickness for a robust depth profile.
• Nonsterile and supplied 100 discs per pack.
• Grade DFAAH, formulated for suspended solids and wastewater analysis.

These discs provide consistent, reliable performance for sample clarification and gravimetric workflows where particulate loads are high. The depth medium protects downstream membranes by capturing coarse particulates upstream, helping preserve sample integrity and extend filter life. Their inert, binder-free composition supports reproducible results across demanding environmental and laboratory applications.
