ChemLab vs MoluCAD

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.

MoluCAD is a free Windows desktop application for molecular modeling and visualization, designed for chemistry students and originally conceived for organic chemistry study. Users can construct molecular structures in true 3D and inspect them from any viewpoint. The software creates reaction animations and includes more than 170 sample structures and animations that can be opened, viewed, and modified. Built-in MM2 energy minimization supports the modeling workflow, alongside an interactive periodic table and HTML-based help. MoluCAD imports and exports PDB, ENT, MOL, and MM3 files, and generates BMP, JPEG, and AVI files. New River Kinematics offers it as a free download through a Windows executable. The product originated in a three-year National Institutes of Health biomedical technology research project intended to produce low-cost chemistry education software. New River Kinematics, founded in 1994 and based in Williamsburg, Virginia, describes itself as an engineering company developing and supporting portable metrology software solutions.
