Grade 151: 0.7 µm - Slow speed. This high performance grade is designed to retain extremely fine particles down to 0.7 µm. Grade 151 has retention comparable to membrane filters while providing higher flow and loading capacity. Grade 151 is recommended for filtering fine precipitated proteins. In the filtration of nucleic acids and difficult biochemical solutions, Grade 151 is used in combination with Grade 141 as a highly efficient protective and retentive pre-filter to extend the loading capacity of membrane 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.
