Thumbnail Filmstrip of Glass Fiber Filters, 2.7um, 70mm, Hydrophilic, Binder-Free, Nonsterile, 100/Pk Images
Featuring a 100% borosilicate glass microfiber depth medium with a 2.7um nominal particle retention, these 70mm binder-free filter discs deliver high particulate loading and fast flow for demanding prefiltration and gravimetric work. The binder-free construction avoids extractables, making the media well suited to solvent filtration and analytical or gravimetric determinations. Each disc measures 0.53mm thick and the hydrophilic borosilicate structure wets readily with aqueous samples.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate structure wets out quickly for consistent aqueous sample handling.
- 2.7um nominal retention captures fine particulates while maintaining fast flow through the depth matrix.
- High particulate loading depth structure with large surface area accommodates heavily loaded samples.
- Binder-free construction avoids binder extractables, supporting gravimetric and solvent filtration accuracy.
- Biologically inert and chemically resistant media stands up to oxidizing agents and weak acids.
Key Construction Characteristics
- Material: 100% borosilicate micro glass fiber, binder-free.
- Diameter: 70mm disc format.
- Thickness: 0.53mm.
- Sterility: Nonsterile.
- Pack: 100 discs per box.
The depth structure provides outstanding impurity retention combined with low filter resistance, helping preserve sample integrity across air monitoring and clarification workflows. With consistent thickness and binder-free media, these discs deliver reliable, repeatable results in gravimetric and prefiltration applications.
