Pyrex Brand Fluted Funnels Save Valuable Minutes

Laboratory technicians specify PYREX brand fluted funnels because they are uniformly fast under all filtering con­ ditions. This feature is a result of their special design. By impressing flutes into the side wall of the funnel blank, a much larger filtering area is ob­ tained. This relieves surface tension and accelerates drainage. Accurately molded to 60°, these

funnels give full support to the filter paper, right down to the apex of the cone. Even when the wet paper cone is loaded with a heavy precipitate there is no sagging of paper, no re­ duction of filtering speed. PYREX fluted funnels are ruggedly built of PYREX brand chemical glass No. 774. They will save time and money for your laboratory. Order them from your dealer's stock.
