About Virtual Lab

Run a free virtual science lab simulator online: titration curves, spectrophotometer scans, microscope slides and molarity prep in real experiment contracts.

Virtual Lab is a free online science lab simulator where you run a real analytical bench. Instead of racing a clock, you work like an actual lab technician: read a contract, pick a sample, choose the right instrument and file a report. Every technique in the game mirrors a real laboratory method used in chemistry and biology labs.

Titration traces a live pH curve as titrant neutralizes your unknown, teaching the equivalence point and why indicator choice matters. The spectrophotometer applies the Beer-Lambert law (A = epsilon c l) so you can quantify colored compounds by scanning wavelengths. The balance station practices molarity math, weighing salts and diluting stock solutions to hit a target concentration, while the microscope station reveals cell morphology at different magnifications. The mixing bench models qualitative analysis, where classic reagent tests like silver nitrate for chloride or iodine for starch produce visible confirmation.

These methods are the backbone of real analytical work: drug quality control, water testing, clinical diagnostics and food safety all rely on the same titration curves, spectra and reagent tests you just ran. Learning to spend reagents efficiently while still getting a correct answer is exactly what separates a good technician from a wasteful one.

How to play

  1. Read the Contract Each contract asks you to identify an unknown or prepare a solution to spec.
  2. Pick a Sample Tap a vial in the rack to load it, then open a station to run tests.
  3. Run Stations Titrate, weigh, scan or view slides. Instruments are free, reagents cost supplies.
  4. Check the Notebook Every measurement auto-logs. Review results before you commit to a report.
  5. File the Report Score = accuracy times supplies saved. Guessing wrong earns nothing!
