Glass Fiber Filters

Glass fiber filters feature fast flow rates, high loading capacity, wide-range thermal tolerance, and excellent precipitate retention. These filters are ideal for gravimetric analyses of air pollutants and serving as prefilters for use upstream of membrane filters. The standard filters for dissolved and suspended solids testing in sanitary water analysis procedures. Glass fiber filters are fabricated from binder-free borosilicate glass fiber with extremely high maximum operating temperatures in air.
