Thumbnail Filmstrip of Glass Fiber Filter Paper Discs, 1.5um Retention, 55mm, Binder Free, Nonsterile, 100/Pk Images
Featuring a binder-free borosilicate glass microfiber depth medium, these 55mm filter discs deliver 1.5um nominal particle retention for demanding aqueous filtration and gravimetric work. The naturally hydrophilic glass fiber matrix provides a large internal surface area that captures fine particulates throughout its depth, combining high impurity loading with low filter resistance for fast, reliable flow.
Key Glass Fiber Media Characteristics
- Constructed from 100% borosilicate glass microfiber that is naturally hydrophilic and wets out instantly with aqueous samples.
- Provides 1.5um nominal particle retention, capturing fine particulates by depth filtration rather than surface screening.
- Binder-free construction avoids binder extractables, making it well suited to gravimetric and analytical determinations.
- Biologically inert and highly resistant to oxidizing agents and weak acids for broad sample compatibility.
- High particulate loading capacity protects downstream membranes and extends final filter life.
Key Construction Characteristics
- Circular disc format in a 55mm diameter for use with standard funnels and filtration holders.
- Nonsterile, supplied 100 discs per pack.
- GVS grade DFAAH glass fiber medium.
This glass fiber depth medium maintains consistent retention and flow across heavily loaded samples, supporting repeatable results in suspended solids and clarification work. Its binder-free structure preserves sample integrity for gravimetric and analytical measurements while withstanding aggressive aqueous matrices.
