Glass Fiber Filters, 1.0um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1215562

Featuring a hydrophilic borosilicate glass fiber depth medium bonded with an acrylic resin binder, these 47mm filter discs deliver a 1.0um nominal particle retention rating for high-volume aqueous filtration and sample clarification. The acrylic binder reduces media migration and provides the mechanical strength needed for filtrations of long duration under pressure. Each disc captures large particulate throughout the depth of the matrix, making it well suited as a prefilter that extends the life of finer downstream membranes or as a standalone clarification medium. This product is supplied nonsterile in a pack of 100.

Key Glass Fiber Media Characteristics

• Hydrophilic borosilicate glass fiber matrix that wets out readily for fast, consistent aqueous flow.
• 1.0um nominal particle retention with high particulate loading capacity for heavily laden samples.
• Acrylic resin binder that reduces media migration and adds strength for filtrations of long duration under pressure.
• Depth-filtration structure ideal for prefiltration to protect and extend the life of finer final membranes.
• Biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids.

Key Construction Characteristics

• 47mm diameter disc format compatible with standard filter holders and funnels.
• Plain grade glass fiber depth medium with acrylic binder.
• Nominal media thickness of approximately 450um.
• Supplied nonsterile, 100 discs per pack.

This glass fiber medium maintains reliable flow and high throughput across demanding particulate loads while preserving sample integrity. Its depth structure traps large particles before they reach the final membrane, supporting efficient serial filtration and dependable clarification. The combination of fine retention and fast flow makes it a versatile choice for laboratory and environmental filtration workflows.
