Thomas 1110-3200 Borosilicate Glass Microfiber Filter, 1.2 Micron, Grade 111, 32cm Diameter (Pack of 100)

Ahlstrom 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. 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. 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 grade offers fine particle retention with high filtration speed and good loading capacity. Ahlstrom 111 is used in general laboratory filtration including atmospheric and water pollution monitoring such as intake controls, ozone-level, and water effluents. Grade 111 is also well suited for filtration of water and protein, testing of algae, bacteria cultures and for radioimmunoassay with weak beta emitters. Ahlstrom 111 is also recommended for filtering solvents in a high-resolution laboratory. Chemical and thermal resistance (up to 500 degree C).
