Glass Fiber Filters and Prefilters

Glass Fiber Filters and Prefilters

Glass fiber filters and pre-filters are used for the filtration of particles from a wide variety of samples. These filters and pre-filters are suitable for various applications requiring capture and removal of contaminating particulates from samples in preparation for downstream purification or analysis.

Made with 100% borosilicate micro-glass fibers. Fisherbrand™ Microglass Fiber Filter Discs are non-hygroscopic and biologically inert. They show chemical resistance to most solvents and reagents (except hydrofluoric acid).
Designed for analysis of non-filterable residue and materials that require a high loading capacity glass microfiber filter. Whatman™ Binder-Free Glass Microfiber Filters, Grade 934-AH Circles are also used in cell harvesting, liquid scintillation, and monitoring pollution.
Moisture test paper for use when drying samples during moisture assessment
For prefiltration and contamination analysis
For prefiltration and contamination analysis
Hydrophilic Glass Fiber without Binder Resin filter
Served as the basis filter for EPA standard for the toxicity characteristic leaching procedure. Whatman™ Binder-Free Glass Microfiber Filters GF/F Circles offers an extremely high loading capacity and flow rate.
Binder-free, borosilicate glass fiber filters have 0.7 micron pore size
Combines fine particle retention with good flow rate. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/C are ideal for the collection of suspended solids in potable water, natural and industrial wastes.
Functions as a prefilter when used with GF/B microfiber filters. Whatman™ Binder-Free Glass Microfiber Prefilters, Grade GF/D provide efficient membrane protection, especially during liquid scintillation counting.
Filters fine particles with high wet-strength and high loading capacity. Whatman™ Binder-Free Microfiber Filters, Grade GF/B Sheets are particularly useful for liquid clarification and liquid scintillation counting.
Ahlstrom Grade 161 is a binder-free microfiber glass filter that offers finer particle retention and higher flow rate than traditional analytical papers.
Faster flow, higher retention than cellulose filters
Made with 100% borosilicate micro-glass fibers and are binder free. Fisherbrand™ Microglass Fiber Filters are particularly suitable for micro-filtration because of very fine fibers.
Offers fine particle retention and high flow rate, as well as good loading capacity
