In their own words
ChemLab
ChemLab is an interactive chemistry lab simulation for high-school and college general chemistry. It pairs simulated experiments with a lab notebook for theory, procedures, and student observations. Pre-designed labs cover subjects including acid-base reactions, electrochemistry, equilibrium, gas laws, kinetics, redox, and stoichiometry, with additional simulations available from third parties. Animated experiments, plug-in lab extensions, and tools to record and replay demonstrations support instruction. Standard lets students run simulations; Professional adds Lab Wizard tools for instructors to run, edit, and create labs, plus an expandable chemical database. Professional users can capture a simulation, add comments, and save a distributable demonstration for Standard users to play back. The product lists RasMol integration and an integrated periodic table application with a quiz. It is described for distance learning, pre-lab work, demonstrations, and lab run-throughs, including experiments that are dangerous, environmentally hazardous, expensive, or lengthy. It is available in English, Spanish, French, and Italian. Single-user Standard licenses start at $33.99, paid once.
