Glass Fiber Filter Discs, 1.2um, 125mm, Nonsterile, 100/Pk
GVS SKU: FP125DMEFCGLFC01

Featuring a borosilicate glass microfiber depth medium, these 125mm circles deliver fast, high-capacity filtration with a 1.2um nominal particle retention. The hydrophilic, three-dimensional fiber matrix loads heavily before clogging, making the discs well suited to turbid and particulate-rich samples where a screen membrane would blind quickly. Each disc measures 125mm in diameter and ships nonsterile in packs of 100.

Key Glass Fiber Media Characteristics

• Hydrophilic borosilicate construction wets out readily with aqueous samples and supports rapid flow at low differential pressure.
• Depth filtration with 1.2um nominal retention captures fine particulate throughout the fiber matrix rather than only at the surface.
• High particulate loading capacity from the large internal surface area extends throughput on heavily loaded samples.
• Chemically robust glass fiber is biologically inert and resistant to oxidizing agents and weak acids.
• Depth medium, not a screen membrane ideal as a prefilter to protect and extend the life of downstream membranes.

Key Construction Characteristics

• Material: borosilicate glass microfiber, grade DMEFC.
• Diameter: 125mm circle.
• Nominal retention: 1.2um.
• Sterility: nonsterile.
• Pack: 100 discs.

These discs maintain consistent flow and retention across high-volume runs, helping preserve filtrate clarity and sample integrity. The inert borosilicate medium minimizes interference with downstream analysis, providing dependable performance in routine clarification and prefiltration workflows.

• Sample Prefiltration Traps coarse and fine particulate ahead of finer membranes to extend final-filter life and maintain flow.
• Environmental Sample Prep Clarifies turbid water and wastewater samples prior to downstream analysis.
• Liquid Clarification Removes suspended solids from heavily loaded aqueous samples for cleaner filtrate.
• HPLC/GC Sample Preparation Pre-filters solvents and samples to protect chromatography systems from particulate carryover.
• Suspended Solids Recovery Captures precipitates and particulates for gravimetric and analytical workflows.
• Air and Aerosol Monitoring Collects fine particulate matter in atmospheric and pollution-control sampling.
