Ahlstrom Binderless Glass Microfiber Filters, Grade 111

Grade 111: 1.2 µm - Fast speed. This grade offers fine particle retention with high filtration speed and good loading capacity. Grade 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 algae, bacteria cultures and for radioimmunoassay with weak beta emitters. 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.
