Glass Fiber Filters, 2.7um, 90mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: FP090DAM27GLFC01

Featuring a binder-free borosilicate glass microfiber depth medium, this 90mm disc delivers a 2.7um nominal particle retention rating built for high particulate loading and rapid flow. The naturally hydrophilic, 100% borosilicate structure provides a large surface area and an open depth matrix that captures fine particulates from air, gases, and liquids while maintaining low filter resistance. With no organic binder present, the medium avoids binder extractables, making it well suited to gravimetric and analytical work as well as air monitoring.

Key Glass Fiber Media Characteristics

• Constructed from 100% borosilicate glass fiber with no binder, eliminating binder extractables for gravimetric and analytical determinations.
• Naturally hydrophilic depth medium with a 2.7um nominal retention rating for capturing fine particulates.
• Depth structure with high surface area provides outstanding impurity retention capacity combined with low filter resistance.
• Biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids.
• High particulate loading capacity makes it effective alone for clarification or as a prefilter to extend downstream membrane life.

Key Construction Characteristics

• Disc format, 90mm diameter.
• Nominal media thickness of 0.53mm (530um).
• Supplied nonsterile.
• Packaged 100 per box.

This glass fiber medium maintains consistent retention and flow across heavily loaded samples, protecting downstream filters and preserving sample integrity. Its binder-free borosilicate composition supports reliable, reproducible results in gravimetric analysis and air monitoring where extractables must be minimized.

• Air Monitoring Binder-free borosilicate construction captures fine airborne particulates and aerosols for atmospheric pollution and air quality measurements.
• Gravimetric Analysis The absence of organic binder eliminates extractables, supporting accurate weighing in gravimetric determinations.
• Sample Prefiltration High particulate loading capacity protects and extends the life of downstream final membranes when filtering heavily loaded samples.
• Suspended Solids Testing The high-capacity depth medium clarifies turbid water and wastewater samples for suspended solids analysis.
• Solvent Filtration Resistance to oxidizing agents and weak acids allows clarification of solvents and aggressive sample matrices.
• Low-Cost Clarification The 2.7um glass fiber medium serves as a standalone clarifier for general laboratory sample preparation.
