Thumbnail Filmstrip of Glass Fiber Filter Paper, 1.2um, 203 x 254mm, Medium Flow, Nonsterile, 100/Pk Images
Featuring a binder-bonded borosilicate glass fiber depth medium, this rectangular filter paper delivers fine 1.2um nominal particle retention at a medium flow rate across a 203 x 254mm sheet. The hydrophilic, biologically inert matrix loads heavily before clogging, making it well suited to clarifying difficult, particle-rich samples and to protecting downstream membranes as a prefilter. Each pack contains 100 sheets.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic depth medium composed of borosilicate glass fibers woven into a porous matrix for rapid, even wetting.
- 1.2um nominal particle retention with medium flow, balancing fine capture against throughput.
- High particulate loading capacity from the depth structure, extending service life on heavily loaded samples.
- Biologically inert and broadly resistant to oxidizing agents and weak acids, and autoclavable for reuse where appropriate.
- Acrylic resin binder reduces media migration and provides strength for high-volume aqueous filtrations.
Key Construction Characteristics
- Format: rectangular sheet, 203mm x 254mm.
- Material: borosilicate glass fiber, FC grade.
- Sterility: nonsterile.
- Pack: 100 sheets per pack.
This depth medium provides consistent retention and reliable flow when handling samples that would quickly blind a screen membrane. The result is dependable clarification and protection of sensitive downstream filtration steps while maintaining sample integrity.
