NEW PRODUCTS All-Glass W a t e r Still A complete, all-glass water still which wall produce high purity water at the rate of 10 liters an hour is available. Called the AG-10, the still is specifi cally designed to fulfill the needs of laboratories requiring a larger capac ity automatic still. A single pass of tap water through the AG-10 produces pyrogen-free water with the high re sistivity of 1.7 megohms, according to the manufacturer. The unit is easily adapted for double distillation proc esses. Manual switches permit op eration at half capacity. Corning Glass Works, Corning, Ν. Υ. 419
Computer Processing of Amino Acid Analyzer Signals The CRS-10D accepts signals in the 1-mv. or greater range directly from amino acid analyzers. I t scans, encodes, digitizes, and tape punches digital sam ple values into IBM 8-track BCD paper tape code. Electrical signals are digi tized directly, eliminating mechanical or electromechanical transducers. Infotronics Corp., 7800 Westglen Drive, Houston, Tex. 77042. 420

ANALYTICAL CHEMISTRY
All-solid-state system for the study of x-ray diffraction features important advancements and advantages over systems currently in use. The chief assets of the system are its relatively low initial cost plus a previously un attainable versatility, convenience, and compactness resulting from the modular solid-state circuitry em ployed. Other major advantages of the system stemming from the solidstate circuitry include higher accu racy, higher levels of stability and re liability, and a great reduction in back ground noise. Automatic data log ging is provided by many methods: paper tape punch, electric typewriter, IBM card punch, printers, recorders, etc. Hamner Electronics Co., P. O. Box 531, Princeton, N. J. 421
