Featuring a borosilicate glass fiber depth medium with an acrylic resin binder, these 25mm filter discs deliver 1.0um nominal particle retention for high-volume aqueous filtration and prefiltration. The naturally hydrophilic media wets out evenly and provides outstanding particulate loading capacity, making it well suited to heavily loaded samples that would quickly blind a screen membrane. The depth structure presents a large internal surface area, combining high dirt-holding capacity with low resistance to flow.
Key Glass Fiber Media Characteristics
- Composed of borosilicate glass fibers woven into a porous matrix and bonded with an acrylic resin, reducing media migration during filtration.
- 1.0um nominal particle retention captures fine particulate while supporting high flow rates.
- Hydrophilic depth structure wets readily with water and aqueous solutions for efficient processing.
- High particulate loading capacity ideal for clarifying turbid or heavily loaded samples.
- Biologically inert and highly resistant to oxidizing agents and weak acids.
Key Construction Characteristics
- 25mm diameter disc format compatible with standard filter holders and funnels.
- Glass fiber with binder construction provides the strength required for high-volume aqueous filtrations.
- Supplied nonsterile in a convenient pack of 100 discs.
This glass fiber medium delivers consistent, reliable retention across demanding filtration runs while protecting downstream membranes from premature blinding. The bonded borosilicate structure resists tearing and minimizes fiber shedding, helping preserve sample integrity and filtrate clarity throughout high-throughput aqueous processing.
