Ahlstrom 1410-0370 Borosilicate Glass Microfiber Filter Paper, 3.1 Micron, Fast Flow, Grade 141, 3.7cm Diameter (Box of 100)

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. Applications for 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. Glass microfiber filters are also found in the filtration of hot gases and liquids, and in pre-filtration. Laboratory analysis, 100 percent pure borosilicate glass, Rapid flow rate, Fine particle retention 0.7 micrometer - 3.1 micrometer, 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 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. Fast Speed, This grade offers better filtration speed and a higher loading capacity than an analytical filter paper of similar particle retention. Grade 141 is particularly recommended for pre-filtration of membrane filters and is also used in combination with Grade 121 as a highly efficient protective and retentive grade density pre-filter for membrane filters.
