Your Du Pont Reagents Distributor has something extra to make your job easier. Your job is easier if there's always someone to answer the phone when ever you need reagents in a hurry. You'll find your Du Pont Reagents Dis tributor ready to deliver any amount, any time. And with 190 others like him around the country, help is close, wherever you are. Your job is also easier when there's no risk of impurity in a reagent. So our rigidly controlled manufacturing conditions assure that each reagent passes multiple tests for the highest quality and uniformity and meets ACS specifications. And your job is easier when you don't have to worry unnecessarily
about accidents. That's why we use one-way carboys for simpler handling and less breakage. And why Du Pont was first with color-coded caps and labels, dripless sleeves, safety grip handles on 5-pint bottles, and a safetyengineered bottle. Now our distributors have some thing extra. A new edition of our Lab oratory Handbook-revised, updated, and expanded over the old one. It's packed with tables, safety precau tions and other facts you use every day. Call him for a copy-and for the facts on the reagents service that makes your job easier. Or just mail the coupon.
