Glass Fiber Membrane Filter Discs, 0.5um, 124mm, Hydrophilic, Nonsterile, 25/Pk
GVS SKU: 1215551

Featuring a hydrophilic borosilicate glass fiber depth medium with an acrylic resin binder, these 124mm filter discs deliver fast, high-volume aqueous filtration at a 0.5um nominal particle retention. The bonded glass fiber matrix provides the mechanical strength required for filtrations of long duration under pressure while reducing media migration into the filtrate. As a depth medium loaded with deep, tortuous flow paths, it captures heavy particulate burdens that would rapidly blind a screen membrane, making it well suited for use as a prefilter or for low-cost standalone sample clarification.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass fiber wets out readily with aqueous samples for consistent flow.
• 0.5um nominal particle retention provides fine retention while maintaining high throughput, not an absolute pore rating.
• High particulate loading capacity from the depth structure handles heavily loaded samples and extends the life of downstream final filters.
• Biologically inert and autoclavable, with high resistance to oxidizing agents and weak acids.
• Acrylic resin binder bonds the glass fibers into a porous matrix, adding strength for high-volume aqueous filtrations and long-duration filtration under pressure.

Key Construction Characteristics

• Format: 124mm diameter disc.
• Media: borosilicate glass fiber with binder.
• Maximum operating temperature: 165 degrees C.
• Sterility: nonsterile.
• Pack: 25 discs per pack.

These discs maintain reliable, repeatable flow across high-volume aqueous and particulate-heavy samples, protecting downstream membranes and preserving sample integrity. The bonded depth structure resists media shedding so the filtrate stays clean, and the inert glass fiber composition keeps the sample chemically unaltered through clarification and prefiltration workflows.
