Thumbnail Filmstrip of Glass Fiber Filter Discs, 1.2um Retention, 110mm, Binder-Free, Nonsterile, 100/Pk Images
Featuring a binder-free borosilicate microfiber depth medium, these glass fiber filter discs deliver fast, high-capacity filtration with a 1.2um nominal particle retention. Each 110mm disc is built from 100% borosilicate glass fibers and measures 0.26mm (260um) in thickness, providing a naturally hydrophilic structure that loads heavily particulate samples without rapid clogging. The absence of any binder makes this medium well suited to solvent filtration and gravimetric analysis where binder extractables must be avoided.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate microfiber wets readily with aqueous samples for consistent flow.
- Depth filtration structure traps particulates throughout the matrix, supporting high particulate loading and fast flow rates.
- 1.2um nominal particle retention for fine retention without the resistance of a screen membrane.
- Binder-free construction minimizes extractables, making it appropriate for gravimetric and analytical determinations.
- Biologically inert borosilicate composition resistant to oxidizing agents and weak acids.
Key Construction Characteristics
- Material: 100% borosilicate glass fiber, binder-free.
- Diameter: 110mm circle.
- Nominal thickness: 0.26mm (260um).
- Sterility: Nonsterile.
- Pack: 100 discs per box.
This depth medium provides reliable, repeatable retention across heavily loaded samples while preserving downstream sample integrity. The high loading capacity protects final membranes from premature clogging and supports demanding aqueous and solvent filtration workflows. With no binder to contribute extractables, the disc maintains clean backgrounds for gravimetric and analytical measurements.
