Featuring a 100% borosilicate glass microfiber depth medium with 1.0um nominal particle retention, these 55mm binder-free filter discs deliver fast flow with high particulate loading capacity. The naturally hydrophilic, binder-free construction avoids extractables, making the medium well suited to gravimetric analysis and air monitoring where sample integrity is critical. Each disc measures 0.28mm in thickness and is supplied nonsterile in a pack of 50.
Key Glass Fiber Media Characteristics
- Constructed from 100% borosilicate glass microfiber with a depth structure that provides outstanding impurity retention capacity combined with low filter resistance.
- Binder-free format is designed for solvent filtration and gravimetric analysis to avoid binder extractables.
- Naturally hydrophilic medium with 1.0um nominal retention captures fine particulates down to 1um in liquids and below 1um in air and gases.
- Biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids.
- High particulate loading capacity makes it ideal as a prefilter to extend the life of downstream membranes or as a standalone clarification medium.
Key Construction Characteristics
- 55mm diameter circular disc format.
- Nominal media thickness of 0.28mm.
- Binder-free borosilicate glass fiber, grade DAM10.
- Supplied nonsterile, 50 discs per pack.
This depth medium maintains consistent retention performance under high particulate loads, delivering reliable clarification while protecting downstream filters.
