These PYREX® Büchner funnels are especially useful where filter paper would be attacked by the materials being filtered. The disc should not be subjected to pressure differential in excess of 1 atmosphere. The top edge is beaded. These funnels are available in three different porosities of PYREX® brand fritted ware so that precipitates varying in size can be filtered at maximum speed with no sacrifice of retention.
