» Buffer 1.0 download web site opinions problem?

Buffer is simple application that will offer you methods of preparation of buffers for a given pH. It accepts a valid pH value and returns one or more methods of preparation of suitable buffers and a number of pH-indicators that change colors close to the pH value entered. Theoretical buffer pH and real buffer pH are usually two different numbers. For best accuracy, it's recommended to use a pH meter. While monitoring the solution's pH, small amounts of either HCl or NaOH in dilute solution are added until the pH reaches the desired value. 4 relevant Internet links dealing with the preparation and pH-calculation of buffers are directly accessible from within the program.  author: Wolf van Heeswijk  required: Windows & Vista  size: 192 k  added: 20-Nov-2009

» ChemToolBox 1.1+ download web site opinions problem?

ChemToolBox, the swiss army knife of the lab worker, is a freeware which contains numerous scientific data very useful in a laboratory. Thanks to its own database, ChemToolBox will easily substitute the time-consuming use of scientific books (such as Handbooks) or online databases. It can provide help in various fields such as; organic chemistry (properties of solvents, miscibility and polarity, cooling mixtures). Solution chemistry (acid/base and RedOx couples, colored indicators, complexes, salts, fluorochroms). Spectroscopy (1H and 13C NMR) or polymer chemistry); biochemistry (amino acids, nitrogen bases, carbohydrates, fatty acids, SDS-PAGE), etc. ChemToolBox also has a full periodic table of elements (with the picture of all elements), a units conversion and calculations module, as well as numerous scientific constants with SI units and derivatives. All these data can be exported in HTML.  author: Julien Nicolas  required: Windows & Vista  size: 11.2 m  added: 13-Jan-2009
