Glass Fiber Filter Discs, 1.2um, 90mm, Binder-Free, Nonsterile, 100/Pk
GVS SKU: FP090DMEFCGLFC01

Featuring a 100% borosilicate glass microfiber depth medium, these binder-free filter discs deliver fine particle retention down to a 1.2um nominal rating across a 90mm diameter format. The naturally hydrophilic depth structure provides a large internal surface area that captures fine particulates throughout the matrix rather than at a single surface, supporting high loading capacity with low filtration resistance. Supplied nonsterile in packs of 100, this medium is well suited to heavily loaded aqueous samples and as a prefilter ahead of finer membranes.

Key Glass Fiber Media Characteristics

• Constructed from 100% borosilicate glass microfiber for broad chemical compatibility and biological inertness
• Binder-free construction minimizes extractables, making it suitable for solvent filtration and gravimetric analysis
• Naturally hydrophilic depth medium that wets readily with water and aqueous solutions
• Nominal 1.2um particle retention with high dirt-holding capacity and fast flow under high particulate loads
• Depth structure traps fine particles throughout the matrix, extending the life of downstream membranes when used as a prefilter

Key Construction Characteristics

• 90mm diameter disc format compatible with standard filter holders and Buchner funnels
• Binder-free borosilicate glass microfiber medium
• Nonsterile
• Packaged 100 discs per box

This depth medium maintains consistent retention and flow even with samples carrying high particulate burdens, protecting analytical integrity and downstream filtration steps. The binder-free borosilicate composition keeps extractables low, supporting reliable gravimetric and solvent-based workflows. Robust loading capacity and rapid throughput make it a dependable choice for demanding clarification and prefiltration tasks.
