Speed Protein Determination With This LABCONCO Team LABCONCO KJELDAHL APPARATUS

LABCONCO TITRATION UNIT

LABCONCO ACID and CAUSTIC DISPENSING UNIT For efficiency in the digestion and distillation phases of protein determination, you can't beat famous Labconco Kjeldahl apparatus. But digestion and distillation are just part of the picture. Adding acid and caustic to your sample and titration are other important steps. Using out-dated methods in the performance of these jobs can be very time consuming, and dangerous . . . if your method involves lifting bottles overhead. With modern Labconco equipment, all solutions can be elevated automatically, all lifting thus eliminated. Why not let us tell you more about the Labconco team for protein determination . . . learn just how much time and work you can save using modern Labconco equipment. Just write . . .

Heffer & Sons, Ltd., Cambridge,. England. 1958. 6 guineas. The Society for Analytical Chemistry, originally The Society of Public Analysts, started publication of The Analyst in 1876. These are the first ten volumes for the years 1876-1885,. republished in facsimile form. During this period, the Society feels, chemical analysis passed to the sphere of an exact science, capable of legal argument and applicable on an industrial scale. The volumes cover the early years of operation of the Sale of Food ancî Drugs Act, 1875, and describe the beginnings of biological examination and the systematizing of water analysis. Then, as now, the journal catered to all classes of analyst. Volume I, for example, contains papers on the analysis of coal and of plating and gilding solutions, as well as reports of work on various foods. Advances in Nuclear Engineering. Volumes I and II. John R. Dunning and Bruce R. Prentice. 1100 pages. Order Dept., The American Society of Mechanical Engineers, 29 W. 39th St., New York 18, Ν. Υ. $35.00 (both volumes). These books based on papers pre­ sented at the 1957 Nuclear Congress, deal \vith the design of nuclear reactors and their cores and the educational use of reactors, metallurgy, instrumenta­ tion, heat transfer, problems of corro­ sion, and related topics. Proceedings of the Congress on Mod­ ern Analytical Chemistry in Indus­ try. 244 pages. W. Heffer & Sons Ltd., Cambridge, England. 1958. 42 shillings. This book of the proceedings of the Congress organized and held June 24 to 28, 1957, by the Scottish section of the Society of Analytical Chemistry, gives all lectures, papers, and discus­ sions, with a list of trade exhibits, com­ mittees, and members of the Congress.
