CORNING® brai —the only wan formulated boroi handle heavily determinations.
Look over the beakers and flasks on these pages and you'll find the ware that lets you handle the toughest problems. Use an octagonal-marked VYCOR® brand flask and you can exploit sudden, drastic tem perature changes that no other ware could withstand. Use a rectangle-marked CORNING® brand beaker and you can go as heavy on the alkali side as necessary. This boron-free ware is 50 times as resistant to alkalies as conventional ware. Use low actinic flasks and you can coddle your light-sensitive solutions in safety. And that still leaves you with all the stand ard PYREX® brand beakers and flasks—the longest, deepest, widest line of lab work horses available. And the best made, too. Look at this Erlenmeyer section and you can see that we keep the glass thick ness uniform to pro vide the uniform strength that means longer service. We add glass at the rim to get a stronger bead. We keep the glass evenly thick through the walls and radii. We keep it from building up too thickly at the bottom so no thermal strength is lost. This longer service is built into every piece in the one line that meets all your beaker and flask requirements. Standardize on this line and you'll find it's easier to qualify for quantity discounts that can save you as much as 28 cents on the dollar.

Micro ware — Lilliputian sizes complement our standard-size lines.
Low a c t i n i c PYREX® brand ware—dark red c o l o r p e r m e a t e s the glass, lets you handle light-sensitive materials safely.
PYREX brand ground joint ware—better than ever, with improved grind and finish on the joints that make them leak less, freeze less than any other.
Approximate gradua tions—we've put white enamel markings on Erlenmeyers and beakers to make m e a s u r i n g chores go faster when absolute precision isn't required.
Screw-cap flasks—lined with inert white rubber, the screw caps make flask handling easier, safer. ^^
•GW Class A—here are measuring flasks that give you unsurpassed accuracy plus the basic strength of all PYREX brand labware—the strength that gives you longer service. Replaceable tubulations —if one of these tubula tions should break, you don't lose the flask as well. Neoprene grommet makes replacement a snap.
