Avitrolab Grade 111 Glass Microfiber Filter Paper

These Avitrolab Grade 111 Glass Microfiber Filter Papers are binder-free and ideal for use in water and wastewater analysis, gravimetric analysis involving ignition of the sample and filtration of hot gases and liquids. They are recommended for use in environmental applications, biochemical testing, as pre-filters, and as direct sample application pads.

Binder-free glass microfibers feature maximum flow efficiency, fine particle retention, while maintaining a higher loading capacity than cellulose filters. Glass microfibers are chemical and thermal resistant and maintain their operational integrity in the presence of acids, alkalis, organic solvents, and temperatures at or above 500°C.
