Start 1970 prepared.... order Sadtler Spectra NOW! W H Y W A I T ? If you are a Sadtler customer, the value in having the latest additions of Sadtler Spectra is obvious — and having them as soon as they are issued will keep you up-to-date. This year, some 8,000 spectra will be added to Sadtler's Commercial Collections, a three-fold increase over last year! Additionally, 9,000 Standard Spectra will be published. Place your order now for these 1970 additions. Better yet, place a standing order for all so you can have them for use as soon as they're issued. If you are not a Sadtler customer, write for information about Sadtler's Standard or Com mercial Spectra (over 120,000 spectra— IR, NMR, UV, DTA) and indices. Inquire, too, about DIGILAB™, the newest concept in computerized instrumentation incorporating IR Fourier transform spectroscopy.
