Glass Fiber Syringe Filters, 0.5um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1215548

Featuring an acrylic resin-bonded borosilicate glass fiber depth medium with a 0.5um nominal particle retention and a 47mm diameter, this hydrophilic filter disc handles heavily loaded aqueous samples that would quickly blind a screen membrane. Composed of borosilicate glass fibers woven into a porous matrix and bonded by an acrylic resin, the bonding reduces media migration and delivers the strength required for high-volume aqueous filtrations. The naturally hydrophilic structure wets out readily and provides high particulate loading capacity, making it well suited for use as a standalone clarification medium or as a prefilter that extends the life of a downstream final membrane.

Key Glass Fiber Media Characteristics

• Depth medium, not a screen membrane: borosilicate glass fibers form a thick porous matrix rated at 0.5um nominal retention, so some particles at or near the rating may pass.
• Hydrophilic: wets out readily for fast bulk flow of water and aqueous solutions.
• High particulate loading: the depth structure traps large particles to increase filtration speed and protect downstream membranes.
• Acrylic resin binder: reduces media migration and adds strength for high-volume and longer-duration pressure filtrations.
• Chemically and thermally robust: biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids.

Key Construction Characteristics

• Format: 47mm diameter filter disc.
• Media: binder (acrylic resin) bonded borosilicate glass fiber.
• Sterility: Nonsterile.
• Pack: 100 discs per pack.

This glass fiber disc provides reliable, repeatable clarification of high-solids and high-volume aqueous samples while maintaining sample integrity. Used alone it offers low-cost sample clarification, and placed ahead of a final membrane it traps large particles before they reach the downstream filter to preserve flow and throughput.

• Prefiltration of Heavily Loaded Samples Traps large particles ahead of a final membrane to extend its life and maintain flow during high-solids filtrations.
• Aqueous Sample Clarification Serves as a low-cost standalone medium for clarifying high-volume water and aqueous solutions.
• Environmental Sample Prep Suited to water and air pollution monitoring where high particulate loading is expected.
• Suspended Solids Analysis Captures suspended solids from water and industrial waste samples for downstream gravimetric or analytical work.
• Protein and Cell Culture Filtration Clarifies protein solutions and algae or bacteria cultures with fast flow and high loading capacity.
• Downstream Membrane Protection Acts as a prefilter to shield fine screen membranes from premature blinding by large particulates.
