» AcaClone pDRAW32 1.1.50 download web site opinions problem?

Freeware DNA cloning, restriction analysis, primer site analysis and visualisation software. pDRAW32 is being developed as a freetime hobby project and it is far from finished, but as it has reached a point where it could be helpfull for many labs, it is now available to the scientific community. pDRAW32 is still in its betatesting stage, and it will probably remain that way for still some years to come. You are free to download and use pDRAW32 at your own risk. The only thing required of you is that you should report any bugs you may encounter.  author: AcaClone Software  required: Windows  size: 3.0 m  added: 24-Jan-2002

» 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

» JVP Periodic Table 4.06 download web site opinions problem?

JVP Periodic Table allows you to access all the elements by Atomic Number, Alphabetical List, or Chemical Series group. Included - All 109 known elements with 2,621 isotopes, half-life, isotopic mass, radioactive decay, particles, complete decay paths and other information. Also includes orbitals, boiling and melting points, atomic radius, bonding radius, chemical series, type classification, ionization, electro negativity, and much more, with a "Fast Facts" page included with the program. This is one of the very few periodic tables which has the isotopes and orbitals. This new version includes "Page Marking" and "MiniCalc" calculator. You still get a GUI format so you don't have to open a browser for HTML, Temporary History Bar at top of page so you don't need a backspace, Find Word or Phrase Function for a single page search, and JVPNote is included as a bonus. Version 4.06 includes a Periodic Table wallpaper. The wallpaper can be downloaded separately and there is also a Periodic Table screensaver available for download.  author: J.V.

» McDalton Learning Edition 1.0 download web site opinions problem?

This is a freeware computer program, designed for learning purposes, to calculate molar or formula masses, the calculations are shown together with the result. Most textbooks include an atomic mass table with values rounded to one or two decimals. For compatibility with answers on examples given in those textbooks McDalton Learning Edition includes the option to use a fixed number of decimals. This may also increase the readability of the output.  author: Christer Svensson  required: Windows  size: 640 k  added: 17-Jun-2004
