SAVE TWO-THIRDS—A kxrge Eastern University cut its replacement costs by two-thirds after it switched to PYREX broad N o . 3046 graduated cylinders.
Test at large university shows how to erase two-thirds of your graduated cylinder breakage When one of the largest schools of technology in this country decided t o find o u t how true a r e the claims we make for PYREX brand graduated cylinders, it came up with this result: Just one PYREX cylinder ends up in the "broken glass1' pail for every tliree of the leading competitive brand. The university based its test on the cylinder-breaking ability of two large groups of chemistry students. One group used only PYREX N O . 3046 cylinders for a full semest r. T h e other group used only the competitive brand.
Why d o you g e t such l o w breakage? N o magic involved—just forty-andthen-some years of know-how that's built into the design of the PVREX N O . 3046 cylinder and the glass it's made off. These design features, lor example: Reinforced bead strengthens cylinder- h e l p s p r e v e n t b r e a k a g e if cylinder tips over. Hexagonal base—a C o r n i n g first—with extra base width to resist tipping. Also prevents rolling when you set cvlinder o n its side.
Permanent graduations You also get L I F E T I M E R E D graduations o n N o . 3046 cylinders. Etched right into the glass through a permanent layer of red. they can't wear off. No. 3046 cylinders are available in sizes 10 thru 250 ml.
