Featuring a binder-free borosilicate glass microfiber depth medium with 1.2um nominal particle retention, these 47mm filter discs deliver fast flow and high particulate loading for demanding clarification and prefiltration work. The naturally hydrophilic, 100 percent borosilicate matrix forms a deep network of fibers that traps fine particulates throughout its 0.26mm thickness rather than only at the surface, providing outstanding dirt-holding capacity with low filtration resistance. As a binder-free grade (Grade FC), the medium avoids binder extractables, making it well suited to gravimetric and analytical determinations where sample purity matters. Each filter measures 47mm in diameter and ships 100 per pack, nonsterile.
Key Glass Fiber Media Characteristics
- Nominal retention: 1.2um nominal particle retention for fine clarification and capture of suspended solids.
- Depth structure: Deep borosilicate fiber matrix loads heavily with particulates while maintaining high flow and low resistance.
- Naturally hydrophilic: Wets readily with aqueous samples without surfactants or pretreatment.
- Binder-free composition: 100 percent borosilicate glass with no bonding resin minimizes extractables for gravimetric and analytical use.
- Chemically robust: Biologically inert and resistant to oxidizing agents and weak acids.
Key Construction Characteristics
- Diameter: 47mm circles.
- Nominal thickness: 0.26mm.
- Grade: FC binder-free glass microfiber.
- Sterility: Nonsterile.
- Pack: 100 discs per pack.
The depth-loading construction maintains consistent flow even as particulate burden increases, protecting downstream membranes and reducing premature clogging. The binder-free borosilicate composition preserves sample integrity for gravimetric analysis and trace-level work. Reliable retention and high loading capacity make these discs a dependable choice for routine and analytical filtration.
