Glass Fiber Filter Discs, 1.6um, 90mm, Air Monitoring, Nonsterile, 100/Pk
GVS SKU: FP090DAM64GLFC01

Featuring a hydrophilic borosilicate glass microfiber depth medium bonded with an acrylic binder, these 90mm filter discs deliver a 1.6um nominal particle retention with a nominal basis weight of 64 g/m2 and a thickness under 0.27mm. The depth structure provides a large surface area for high impurity retention capacity combined with low filter resistance, making the media well suited to air and gas monitoring and other heavily loaded sampling tasks. The acrylic binder reinforces the borosilicate matrix, reduces media migration, and adds the strength needed for high-volume filtration.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass microfiber that wets out readily for consistent sampling
• Depth medium structure delivers high particulate loading capacity with low resistance to flow
• 1.6um nominal particle retention suited to air monitoring and high-flow sample collection
• Acrylic binder reinforces the matrix, reduces media migration, and supports high-volume filtration
• Biologically inert, autoclavable borosilicate construction resistant to oxidizing agents and weak acids

Key Construction Characteristics

• 90mm diameter disc format for standard filter holders and monitoring assemblies
• Nominal basis weight of 64 g/m2 with a thickness under 0.27mm
• Nonsterile, supplied 100 discs per pack

This depth medium maintains reliable retention of fine particulates and aerosols while preserving sample integrity for downstream analysis. The robust borosilicate matrix withstands demanding sampling conditions and protects measurement accuracy across repeated use.

• Air Pollution Monitoring Collects airborne particulates and aerosols for atmospheric monitoring and gravimetric analysis.
• Aerosol Sampling Captures fine particles below 1um in air and gas streams thanks to the electrostatic interaction of the glass fiber depth medium.
• High Particulate Load Prefiltration Handles heavily loaded samples with high loading capacity and low flow resistance to protect downstream filters.
• Suspended Solids Analysis Recovers suspended solids from aqueous samples for environmental and industrial monitoring.
• Environmental Sample Preparation Clarifies and conditions environmental samples ahead of instrumental analysis.
• General Particulate Removal Removes particulate matter from liquids using a hydrophilic borosilicate depth structure.
