Thumbnail Filmstrip of Glass Fiber Filter Discs, 1.5um Retention, 24mm, Binder-Free, Nonsterile, 100/Pk Images
Featuring a binder-free borosilicate glass microfiber depth medium, these 24mm filter discs deliver a 1.5um nominal particle retention with the high loading capacity and rapid flow characteristic of a glass fiber depth structure. The naturally hydrophilic media wets quickly with aqueous samples, and the absence of binders avoids extractables that could interfere with gravimetric or analytical determinations. Each disc measures 0.28mm (280um) thick and is supplied nonsterile in a pack of 100.
Key Glass Fiber Media Characteristics
- Nominal particle retention of 1.5um across a random borosilicate fiber matrix that traps particulate throughout the depth of the medium rather than at a single surface screen.
- Naturally hydrophilic structure for fast wetting and high flow with aqueous solutions and suspensions.
- Binder-free construction made from 100% borosilicate glass fibers, avoiding binder extractables for cleaner gravimetric and analytical work.
- High particulate loading capacity well suited to heavily loaded samples and to extending the life of downstream final filters.
- Biologically inert and chemically robust against weak acids and oxidizing agents.
Key Construction Characteristics
- Format: circular filter disc, 24mm diameter.
- Nominal thickness: 0.28mm (280um).
- Sterility: nonsterile.
- Pack: 100 discs.
The depth structure provides consistent particulate capture while maintaining fast flow, helping preserve sample integrity through demanding clarification and prefiltration steps. With no binders to leach into the filtrate, these discs support reliable, reproducible results in gravimetric and analytical applications.
