Glass Fiber Filter Discs, 0.5um, 22mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215543

Featuring a borosilicate glass fiber depth medium bonded with an acrylic resin binder, these 22mm filter discs provide a 0.5um nominal particle retention for demanding aqueous filtrations. The woven porous matrix offers a large surface area and high dirt-holding capacity, making it well suited for heavily loaded samples that would quickly blind a screen membrane. The hydrophilic structure wets out readily with water and aqueous solutions, while the bonded construction reduces media migration and adds the strength required for high-volume filtration. Each pack contains 100 nonsterile discs.

Key Glass Fiber Media Characteristics

• Hydrophilic borosilicate depth medium composed of glass fibers woven into a porous matrix for rapid wetting with aqueous solutions.
• 0.5um nominal particle retention captures fine particulate throughout the depth of the medium rather than at a single surface plane.
• High particulate loading capacity traps large particles before they reach a final membrane, extending downstream filter life.
• Acrylic resin binder reduces media migration and provides strength for high-volume aqueous filtrations of long duration under pressure.
• Biologically inert and autoclavable with high resistance to oxidizing agents and weak acids.

Key Construction Characteristics

• Format: 22mm plain filter disc.
• Media: glass fiber with acrylic resin binder.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

The depth structure delivers consistent flow and reliable particulate removal across high-load samples, helping protect and prolong the life of downstream membranes. The bonded glass fiber matrix maintains its integrity under pressure, supporting sample throughput without media shedding. These discs offer a dependable, low-cost option for clarification and prefiltration where sample integrity matters.

Hydrophilic

• Sample Prefiltration Traps large particles from heavily loaded samples before they reach a final membrane, increasing filtration speed and extending downstream filter life.
• Sample Clarification Serves as a standalone, low-cost depth filter for clarifying turbid aqueous solutions.
• Environmental Sample Prep Handles high particulate loads common in environmental and field samples prior to analysis.
• High-Volume Aqueous Filtration The acrylic-bonded matrix withstands long-duration filtrations under pressure for large sample batches.
• Downstream Membrane Protection Used inside a filter holder to shield finer membranes from premature blinding by coarse particulate.
