This glass microfiber grade is a smooth surface, binder-free filter with unique high temperature resistance. It offers fine particle retention and product stability to over 500 degrees Centigrade. The temperature resistance makes Grade 169 well-suited for TCLP test methods, suspended solids determination, volatile solids testing, air pollution testing, and related EPA and ASTM protocols.

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.
