Never before so
SKTTEEHUF NALGENE® PLASTIC LABORATORY BOTTLES Drop them! Bounce them! Nalgene poly ethylene bottles won't shatter, ever! Their premium resins and punishment-proved de· sign save you the known costs of breakage and replacement—plus the incalculable costs of injury or loss of valuable contents. There have never before been laboratory bottles so shatterproof, so leakproof, so acidsafe. That's because these are the only bottles and closures ever developed specifically for laboratory use. It will pay you to know more about Nalgene bottles. Ask your lab supply dealer. And look for this ^ symbol of quality on the bottom of every Nalgene bottle. For our new catalog of the complete line of bottles, jars and carboys, in sizes from 1 ounce to 13 gallons (including Nal^ gene polypropylene bottles, heat\ resistant for repeated autoclaving), write Dept. 2617.
