Thumbnail Filmstrip of Glass Fiber Filter Paper Discs, 1.5um, 110mm, Binder-Free, Nonsterile, 100/Pk Images
Featuring a 100% borosilicate glass microfiber depth medium with no binder, these 110mm circles deliver fast, high-capacity filtration with a 1.5um nominal particle retention. The hydrophilic, three-dimensional fiber matrix loads heavy particulate without rapid blinding, making it well suited to turbid aqueous samples and gravimetric work where binder extractables must be avoided. Each disc is supplied nonsterile in packs of 100.
Key Glass Fiber Media Characteristics
- Binder-free borosilicate construction avoids extractables for clean gravimetric and analytical determinations.
- Naturally hydrophilic depth structure wets readily and provides a large internal surface area for impurity retention.
- 1.5um nominal particle retention captures fine suspended solids while maintaining a rapid flow rate and low filter resistance.
- High loading capacity handles heavily loaded and turbid streams, extending run times on difficult samples.
- Biologically inert and resistant to oxidizing agents and weak acids, and autoclavable for reuse-tolerant workflows.
Key Construction Characteristics
- Format: 110mm diameter circle.
- Grade: DFAAH binder-free glass microfiber.
- Wettability: hydrophilic.
- Sterility: nonsterile.
- Packaging: 100 circles per box.
The pure borosilicate matrix maintains consistent retention and low fiber shedding across high-volume filtrations, supporting reproducible results in suspended solids and pollution monitoring. With its high flow rate and loading capacity, this disc clarifies challenging samples while protecting downstream membranes and preserving sample integrity.
