Grade 161 Glass Microfiber Filter Papers
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. Laboratory analysis 100% pure borosilicate glass Rapid flow rate Fine particle retention 0.7µm – 3.1 µm High loading capacity Chemical and thermal resistance (up to 500°C) Long shelf life Brilliant white color reflecting more than 96% of visible light Custom cut Standard Glass Microfiber Filters Standard glass microfiber filters contain no binders or other additives that may cause interference to sensitive enzymatic or other chemical reactions. The unique characteristics of glass microfiber filters make its use particularly advantageous to laboratory filtration by enabling fast filtration of large volumes and difficult solutions without premature clogging. Ahlstrom 161: 1.1µm – Medium Speed 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.
