Thumbnail Filmstrip of Glass Fiber Filter Discs, 1.5um, 240mm, Binder-Free, Slow Flow, Nonsterile, 100/Pk Images
Featuring a 100% borosilicate glass microfiber depth medium, these binder-free filter discs deliver a 1.5um nominal particle retention across a 240mm diameter format. The hydrophilic, binder-free construction provides a large internal surface area and slow flow characteristics suited to demanding gravimetric and suspended-solids work, while avoiding binder extractables that can interfere with sensitive analyses. Each pack contains 100 nonsterile discs.
Key Glass Fiber Media Characteristics
- Binder-free borosilicate construction avoids binder extractables, making the medium well suited to gravimetric analysis and solvent filtration.
- Naturally hydrophilic depth medium wets out readily with aqueous samples and captures particles throughout its thickness rather than only at the surface.
- 1.5um nominal particle retention with a slow flow profile balances fine retention against high particulate loading capacity.
- High loading capacity handles heavily loaded samples and extends the life of downstream membranes when used as a prefilter.
- Biologically inert and chemically robust with resistance to oxidizing agents and weak acids.
Key Construction Characteristics
- Format: 240mm diameter circular filter disc.
- Material: 100% borosilicate glass microfiber, binder-free.
- Sterility: Nonsterile.
- Pack: 100 discs per pack.
The depth structure provides consistent, repeatable particle capture for high-volume and heavily loaded samples while maintaining low filter resistance. Its binder-free, inert borosilicate composition helps preserve sample integrity in gravimetric and trace-level work. These characteristics make it a dependable choice for suspended-solids and clarification workflows.
