Ahlstrom 1610-1420 Borosilicate Glass Microfiber Filter Paper, 1.1 Micron, Medium Flow, Grade 161, 14.2cm Diameter (Box of 100)

Offers a full range of glass microfiber filters manufactured from 100 percent 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. 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. It is also found in the filtration of hot gases and liquids, and in pre-filtration. Laboratory analysis, 100 percent pure borosilicate glass, rapid flow rate, high loading capacity, chemical and thermal resistance (up to 500 degree C), long shelf life, brilliant white color reflecting more than 96 percent 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. This popular grade offers finer particle retention and higher flow rate than traditional analytical filter papers. Grade 161 is used in general laboratory applications, cell harvesting, liquid scintillation counting, and in the monitoring of air and water pollution. Grade 161 is generally recommended for water pollution monitoring techniques for total suspended solids.
