SYMBOLS OF SERVICE F o r thirty-one years, the A m e r i c a n Chemical Society "Committee on Ana lytical Reagents" has served the chem ical profession well. Its specifications governing reagents "suitable for careful analytical work" are the universally ac cepted standards by which laboratory c h e m i c a l s are j u d g e d . The mark "A. C. S." on a reagent is symbolic of highest chemical quality and uniformity.
REAGENTS
Since the first A. C. S. specification was written, Baker & A d a m s o n has m a d e these impartial standards of the chemical profession its guide in reagent manufac ture . . . recognizing that rigid adherence to predetermined specifications is the essence of uniformity so necessary in reagents. And, where A. C. S. specifications do not exist, B&A has established its own
equally strict standards of purity—thus continuing its policy, born 67 years ago, to bring America's chemists the finest in laboratory chemicals. In such a way, B&A continues to serve . . . and to set the pace in chemical purity. The high regard in which chemists hold reagents bearing the B&A "Shield of Quality" is more than a point of pride ; it is a responsibility always to be upheld.
