Its spreadsheet holds up to 32,765 Chemical Inventory System, designed specolumns and more than 2 billion rows, and cifically for tracking chemicals and other
necessary supplies in the laboratory, maintains information about chemical names, CAS registry numbers, and chemical formulas, as well as vendor and catalog numbers, storage locations, and quantities of two defined container sizes (e.g., bottles and cases). Chemicals and other supplies can be sorted by name, CAS registry number, description, vendor, location, or chemical formula. Simple listings or detailed reports for any given chemical, supply, or group of items can be generated, including all relevant vendor information and on-hand quantities. The program runs on PC compatibles and requires a minimum of a 386 CPU, 4 MB RAM, 6 MB hard disk space, and Windows 3.1 or higher. A multiuser version that offers full network support is also available.

Kinetics for Windows is designed to model complex chemical reactions and reaction mechanisms. Its Windows interface allows users to input complex chemical systems by typing the reaction equations and associated rate constants. The program automatically formulates the differential equations that are necessary to describe the kinetics of the chemical system under study. The rate equations are then numerically integrated using a modified GEAR algorithm. Chemical systems containing up to 100 reversible reactions can be evaluated, mechanisms with individual reactions as high asfifthorder can be examined, computations on systems containing up to 50 chemical species are possible, and a plotting routine is included for viewing the results of the program. Minimum system requirements include an 80386 PC running DOS 5.0 (or later) and Windows 3.1,2 MB RAM, and VGA display. A math coprocessor is recommended but not required.
