FREE SCIENTIFIC consumables TO DOWNLOAD

You may freely download, use and distribute unmodified copies of the following freeware programs. However, please note that the respective authors retain copyright of the consumables. The programs may not be sold or distributed for profit.

AcidBaseLab  

AcidBaseLab is a titration curve calculation program that can be used to simulate real titration experiments.

This program does much more than simply calculating the pH of a strong or a weak acid (or base).

Instead, it can perform ANY pH calculation, independent of the complexity of the composition under consideration.

During titration, the colour (changes) of the solution can be monitored. Moreover, you can simply edit the list of possible acid/base chemicals as well as the pH-indicator list to match your specific needs.

Atomic Models  

Atomic Models allows you to visualize the atomic models of Rutherford, Bohr, and Schroedinger.

Atomic Models consists of three separate programs which represent the various models.

Calc 98  

Well over a million PC users are using Calc 98, the popular engineering, scientific and financial calculator for Windows.

The calculator includes functions for statistics, use of different number bases (binary, octal, hexadecimal and base-n), metric unit conversions, physical properties and constants.

Calc 98 offers a number of financial functions including investment, loan and savings calculations.

The program also features a number of time functions, including a useful stopwatch.

CChemistry  

CChemistry displays information about the first 103 elements of the Periodic Table.

You simply select an element's name or symbol from the list, and the element's name, symbol, number, and weight are displayed.

ChemBalance  

ChemBalance Wizard (32-bit) accepts up to 10 chemical species as input and produces one or more balanced chemical equations.

If no balanced equations exist for the given species, you are informed that none can be produced.

The rapid balancing of the chemical equations makes this program a useful tool for students and teachers alike.

Chemistry Assistant  

Chemistry Assistant is an expression calculator for the fast calculation of the molecular weight of compounds by simple entry of chemical formula.

The program translates the texts with chemical element symbols (or without them) into a mathematical expression and then calculates them.

The program includes functions for statistical analysis, solving the quadratic equation and a solution preparation calculator.

The element symbols can be written in lower case letters. The program will try to translate them and will show the result of the translation - or it will report an error.

The appearance of mathematical expression, which is the result of the translation, can be seen if the mouse pointer is held over the tasks field. The right mouse button shows several often used anions and molecules.

Conversion 2  

An extremely useful program covering more than 3500 conversions between metric and SI units.

Converts length, volume, weight, temperature, surface, density, power, pressure, work, efficiency, angle, time, speed and flows.

GraphTablet  

GraphTablet generates rectangular, polar and semilog graph paper on your own colour printer.

An intuitive interface allows control over major and minor divisions, pen colour, width and layout.

You can also choose to display 1, 2 or 4 separate grids per page.

Periodic Library 1.8a  

Periodic Library 1.8a is a periodic table of the elements that offers far more than just a computerised version of the standard periodic table.

The program takes full advantage of your computer's capabilities to give an in-depth and inter-active look at the elements.

Periodic Table of the Elements  

Periodic Table of the Elements contains the basic data about the elements in 7 languages (English, German, French, Italian, Spanish, Portuguese and Croatian).

It graphically illustrates the change of physical condition with the change of temperature.

The language required, the speed of temperature change, the exchange of elements or the scrolling of characteristics can all be adjusted via the configuration file.

The calculating module from the program Chemistry Assistant for calculating the mole mass of compounds, has also been integrated into the Periodic Table.

The programme translates entered texts with chemical symbols (or without them) into mathematical terms and then calculates them.

The Periodic Table can be incorporated into a presentation, the change of temperature automatically started and the programme closed. The colour of the background can also be adjusted to match the colour of the presentation slide.
