Thumbnail Filmstrip of Glass Fiber Filter Paper Discs, 1.2um, 150mm, Binder-Free, Nonsterile, 100/Pk Images
Featuring a 100% borosilicate glass microfiber depth medium manufactured without binder, these 150mm filter paper discs deliver fast flow with fine nominal particle retention down to 1.2um. The hydrophilic, binder-free construction avoids binder extractables, making the discs well suited to gravimetric and analytical determinations where sample purity is critical. Each disc measures 150mm in diameter with a nominal thickness of approximately 0.27mm, and the discs are supplied nonsterile in packs of 100.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate glass microfiber wets out readily for consistent aqueous filtration.
- Depth filtration structure with a large surface area provides high impurity retention capacity combined with low filter resistance.
- High particulate loading capacity makes the medium ideal for heavily loaded samples and prefiltration ahead of finer membranes.
- Binder-free composition eliminates binder extractables for analytical and gravimetric work.
- Biologically inert and chemically resistant, withstanding oxidizing agents and weak acids, and autoclavable.
Key Construction Characteristics
- Material: binder-free borosilicate glass fiber (Grade FC).
- Format: 150mm diameter flat disc.
- Nominal retention: 1.2um.
- Sterility: nonsterile.
- Pack: 100 discs per box.
These discs maintain reliable, reproducible flow across high-volume aqueous filtrations while protecting downstream filtration steps from heavy particulate loads. The pure borosilicate composition supports sample integrity in gravimetric and analytical procedures. With fine nominal retention and fast flow, the medium clarifies challenging samples efficiently.
