What is Chemix?
Chemix is an online educational app and drag-and-drop editor for drawing scientific lab diagrams and school experiment apparatus. It provides a large library of highly customizable lab equipment including chemistry glassware, physics components, and biology tools, allowing users to create detailed experimental setups quickly. The tool is designed for students, teachers, researchers, and anyone who needs to illustrate scientific experiments for lab reports, teaching materials, presentations, or publications.
Key features include smart detection of chemical formulas and units that automatically formats text as you type, multi-layer liquid support for separation and titration experiments, shape snapping for precise alignment, and cloud storage to save and edit diagrams from any device. Users can rotate containers with levelled liquids, change item properties like size and color, add labels and arrows, and export images in multiple formats. The physics release adds optics and electric/magnetic components, while the chemistry library includes specialized items like Schlenk flasks, rotary evaporators, and distillation apparatus.
Chemix is particularly valuable for chemistry educators creating lab diagrams for titrations, distillations, and other common setups. The platform offers both free and paid tiers, with the free version providing access to 159 pieces of apparatus and the paid Boost plan unlocking additional items and premium features. Diagrams can be downloaded as JPG, transparent PNG, or SVG files, and the tool supports multiple languages including English, French, German, and Spanish.
Chemix pricing
Pricing model: Freemium
Chemix offers a freemium model. The Free tier is $0/month and includes access to 159 pieces of apparatus, standard quality image export (800x600), 3 cloud diagrams, and most core features. Images created belong to you for use in teaching materials and presentations. The Boost paid plan costs $2.79/month (£2.39/month) and unlocks: all 188 apparatus items, high-quality 1600x1200 image export (8x more pixels), SVG vector export, 150 cloud diagrams, smart detection of formulas and units without the 7-letter limitation, additional customizations on items (filter paper types, hazard signs, crystal shapes, thermometer sizes, gas cylinder types), and more liquid layers in containers. A 7-day free trial of Boost is available. Schools and universities can get discounted licenses with pricing based on number of pupils.

Frequently asked questions about Chemix
What is Chemix used for?
Chemix is an educational app that lets you easily draw lab diagram setups and explain experiments. It has a large library of highly customizable apparatus for chemistry, physics, and biology. Students use it for lab reports and research papers, while teachers create diagrams for instructions, teaching materials, presentations, and YouTube videos.
Is Chemix free to use?
Yes, the Free tier lets you use most of the app for free. You get access to 159 pieces of apparatus, standard quality image export, and 3 cloud diagrams. Images you create belong to you and can be used in teaching materials and presentations. The Boost subscription unlocks additional items and premium features but is optional.
How do I add items to my diagram?
The list of apparatus is on the left side of the interface. Scroll through the list and select an item to add it to the canvas. Once selected, a property panel opens on the right where you can change properties like size, color, and rotation depending on the item.
What image formats can I export?
You can download images in JPG, transparent PNG, and SVG formats. The free version exports at standard quality (800x600 resolution), while the paid Boost plan unlocks high-quality export (1600x1200 with 8x more pixels) and SVG vector format for lossless scaling.
How does the smart formula detection work?
This unique Chemix feature automatically formats chemical compounds, formulas, and units as you type normally. Just type things like 'mol L^-1' for molar concentrations, '10_2' for subscripts, '10^2' for exponents, and 'oC' for degrees Celsius. Chemix intelligently figures out the formatting without needing to use complicated interfaces.
Can I save and edit diagrams later?
Yes, you can save diagrams to the Chemix Cloud and open them later to edit, export, or print from any device anywhere. The free plan allows 3 cloud diagrams, while the Boost plan allows up to 150 diagrams in the cloud. You must create an account first to use cloud storage.
What apparatus items are in the paid plan?
The Boost plan unlocks 29 additional items including Schlenk lines, Burette holder, Fluted Filter Paper, Rotavap (rotary evaporator), and other specialized chemistry equipment. It also adds additional customizations like side-arms on dropping funnels, more crystal shapes, thermometer sizes, collar on Bunsen burner, and extra gas cylinder types.
Can I use Chemix diagrams commercially?
Yes, images you create belong to you. For non-commercial use within a small setting (fewer than 100 people) like class handouts, no attribution is required. For mass/public non-commercial use or any commercial use, attribution to Chemix as the tool used is required unless you upgrade to a subscription, which exempts exported images from attribution requirements.
Does Chemix support physics and biology diagrams?
Yes, Chemix expanded beyond chemistry to include physics and biology items. The physics release includes electric and magnetic items (powerpack, ammeter, voltmeter, resistor, LED, magnet, solenoid) plus optics items (convex/concave lenses, mirrors, prism, ray box). Biology has 20+ items suitable for biology experiments.
How do I upgrade to the Boost plan?
First make sure you are logged in, then click on 'My account' in the interface. Click on 'Upgrade plan' and select the 'Boost' plan to upgrade. You can also sign up for a 7-day free trial of the additional features before committing to the subscription.
