A chemistry virtual lab that runs in your browser
Every experiment written as a single web page. No plugin, no download, no account. Open one, and once it has loaded it keeps running even if your connection drops - which matters if you are working from a phone on patchy data.
Open the digital labTopic by topic
Grouped by topic below. Every one is built from the real chemistry: measured volumes, real electrode potentials, real reaction rates, so the numbers you read off are the numbers you would get.

Common questions
What is a chemistry virtual lab?
A simulation of laboratory apparatus that behaves the way the real thing does. You set the conditions, start the reaction and read the instruments. The point is repetition and safety: you can run a reaction that would be dangerous, expensive or slow in a school lab, and you can run it again the moment it goes wrong.
Do I need to install anything or make an account?
Neither. Each experiment is a web page. Click it and it opens. Nothing is stored about you.
Does it work on a phone?
Yes. Every lab is laid out for a phone as well as a desktop, and the wider benches have a rotate button so you can use the screen sideways where that helps.
Which syllabuses do these follow?
Cambridge IGCSE Chemistry 0620 and CBSE Classes 9 to 12 primarily, with the physical and inorganic labs also useful for JEE and NEET. Each experiment lists its level on its own page.
Is it really free?
Yes. Every simulator on this site is free to use with no limits and no sign-up. Paid tuition is a separate thing.
Studying something else?
The same labs, grouped for a different syllabus.
