Featuring a binder-free borosilicate glass microfiber depth medium, these 37mm filter discs deliver a 1.5um nominal particle retention for fast, high-capacity clarification of heavily loaded aqueous samples. The depth structure traps fine particulates throughout the media rather than at a single screen surface, providing high loading capacity with low filter resistance. Each filter is naturally hydrophilic, biologically inert, and free of binders, making it well suited to gravimetric and analytical determinations where binder extractables must be avoided. Supplied nonsterile in a pack of 100.
Key Glass Fiber Media Characteristics
- Provides a 1.5um nominal particle retention for fine particulate capture with fast flow.
- Constructed from 100% borosilicate glass fibers with no binder, eliminating binder extractables for gravimetric and analytical work.
- Naturally hydrophilic depth structure delivers high particulate loading capacity and low filtration resistance.
- Biologically inert and highly resistant to oxidizing agents and weak acids.
- Functions alone for low-cost sample clarification or as a prefilter to extend the life of downstream membranes.
Key Construction Characteristics
- 37mm diameter circle format for use in standard filtration holders and funnels.
- Binder-free borosilicate glass microfiber media throughout.
- Autoclavable for applications requiring clean media.
- Supplied nonsterile, 100 discs per pack.
These depth filters maintain consistent retention and flow across high-solids samples, protecting downstream membranes and instrumentation from premature fouling. The pure borosilicate composition supports reliable gravimetric results and preserves sample integrity throughout demanding clarification and analysis workflows.
