Glass Microfiber Filter, 24 cm dia, Brilliant White, Grade 161, Standard Grade Type, Circle Format, 0.317 mm Thickness, 1.1 µm Particle Retention in Liquid, 68 g/m2 Nominal Basis Weight, 67 sec/100 ml (Herzberg) Filtration Speed
Ahlstrom offers a full range of glass microfiber filters manufactured from 100% pure borosilicate glass. Because of their intrinsic properties, glass microfiber filters have wide applications in many areas of laboratory analysis, especially when fine filtration and high loading capacity is required. Applications for Ahlstrom glass microfiber filters include environmental analysis for water, wastewater, testing of soils, air pollution and monitoring, research and process biochemistry and gravimetric analysis involving ignition of samples. Ahlstrom glass microfiber filters are also found in the filtration of hot gases and liquids and in pre-filtration. This popular grade offers finer particle retention and higher flow rate than traditional analytical filter papers. Ahlstrom 161 is used in general laboratory applications, cell harvesting, liquid scintillation counting and in the monitoring of air and water pollution. Ahlstrom 161 is generally recommended for water pollution monitoring techniques for total suspended solids.
