Grade D

Grade D microfiber filters have a coarse porosity and fast flow rate with a 2.7µm size particle retention. Grade D filters are well suited for higher volume and repetitive laboratory filtering. Also ideally used as a general pre-filter to extend primary filter life. All filters are binderless borosilicate glass microfiber.
