NEW SCREW CAP VOLUMETRIC FLASK SEALS TIGHT! WONT FREEZE! COSTS LESS! The Bakélite* screw cap on this new volumetric flask holds tight, can't pop off. Its conical polyethylene liner hugs the flask neck, seals it tight, won't leak a drop. Alkalies can't freeze it. If you upset the flask, the cap takes much of the shock. In storage, the cap keeps dust and dirt off the flask lip. No. 5650 flask with cap closure costs from 40 cents to $1.00 less
than similar types with glass stoppers. The 25 and 50 ml sizes fill quicker and easier because of their funnel necks which also serve as mixing chambers. Six other sizes too: 100 thru 2000 ml. All are Class A accuracy. All are made of PYREX® brand glass to shrug off chemical attack, mechanical shock. There are 16 other PYREX brand volumetric flasks for your work . . . flasks with or without stoppers, in
different styles and capacities. You will find the world's biggest, widest, broadest line of labware in our LG-2 catalog. Remember, too, the quantity discounts—up to 23.5%. *Union Carbide Trademark
