2.3. Chemical database

When program is starting the Database window will appear to the right of the main window to help you add frequently used chemicals. By choosing a chemical the Database window automatically closed. You can bring it back up by clicking on the Show Database button (F9).

The window is divided in to two parts. A database with the 175 most common chemicals found in a laboratory is found at the top part of the window. Almost three quarters of chemicals in the database have a formula for calculating density. Each formula have a correlation coefficient value (R2) greater than 0.9999 in the concentration range listed in the table below.

By clicking on the name of a column you can sort chemicals by their names or formulas. Clicking again will sort them in reverse order. If a hydrate is the usual form of the chemical it will be automatically added to the Source field.

The bottom part of the screen shows the hazards of a material with NFPA diamond. Chemical name, formula, and CAS number allows accurate identification of selected chemicals.
