Draw, calculate and document
your chemical reactions
without leaving your notebook
The new Reaction Workbench brings a modern reaction editor directly into LabCollector ELN. Build publication-ready schemes and the stoichiometry that goes with them — all connected to your chemical inventory.
A clean scheme in seconds
Combine reactants, conditions and products in a single panel. The scheme and stoichiometry table are inserted automatically into your page.
Stoichiometry Table
Recalculated in real time| Compound | MW | Eq | Moles | Mass | Volume |
|---|---|---|---|---|---|
| Bromobenzene | 157.01 | 1.2 | 1.20 mmol | 188.4 mg | — |
| Boronic acid | 122.93 | 1.0 | 1.00 mmol | 122.9 mg | — |
| Pd(PPh₃)₄ | 1155.56 | 0.05 | 0.05 mmol | 57.8 mg | — |
| K₂CO₃ | 138.21 | 2.0 | 2.00 mmol | 276.4 mg | — |
| Dioxane/H₂O | — | — | — | — | 5.0 mL |
The scheme and table are inserted as a smart snapshot — double-click to reopen and edit the reaction at any time.
Everything you need, in one panel
An interactive tour of the Reaction Workbench — click a keyword to explore each feature.
A draggable, resizable panel opens right on your page. Compose a full reaction — reactants, reagents/conditions above the arrow, products — then insert a clean scheme and data table in one click.
Everything in one panel
A draggable, resizable panel opens right on your page. Compose a full reaction — reactants, reagents/conditions above the arrow, and products — then insert a clean scheme and data table into your experiment in a single click.
- Floating draggable panel
- Scheme + data table in one click
- No external software required
Draw or reuse — your choice
Draw structures natively with the built-in MolEdit editor, or pull existing molecules straight from your Chemical Structures module. You'll never redraw the same compound twice.
- Built-in MolEdit editor
- Import from Chemical Structures
- No duplicated work
Live stoichiometry & yield
Automatic molecular weight and formula, limiting reactant detection, equivalents, moles, mass/density/volume, molarity for dissolved solids, and theoretical/actual yield with purity — all recalculated as you type.
- Automatic MW & formula
- Limiting reactant detection
- Theoretical & actual yield with purity
Always re-editable
Inserted reactions are smart snapshots: double-click any reaction in a page to reopen and refine it. Each reaction carries its own data, staying intact no matter what happens to templates later.
- Double-click to re-edit
- Self-contained data per reaction
- Intact even after template changes
Work faster with templates
Reusable templates
Save any reaction as a template, with versioning, author and date.
Instant reload
Reload a template into the workbench in seconds to start a new experiment.
Full traceability
See exactly where each template is used across your books and pages, with clickable links.
Import from ChemDraw and beyond
CDXML & SMILES
Drag-and-drop a ChemDraw CDXML file or paste a reaction SMILES. The workbench parses the whole scheme.
Inventory auto-match
Imported structures are automatically matched to your Chemical Structures inventory (by structure, formula, weight) and linked.
Guided loader & preview
A clear loader and preview guide you at every import, with a vendor-neutral engine extensible to RXN.
Designed for real laboratories
Connected to inventory
Reactions automatically populate the LabCollector Data links on your page, keeping traceability between experiments and the molecules used.
Global-ready
The workbench is fully translatable: English, French, Spanish, German and Portuguese.
Zero friction
No desktop software, no plugins to install — everything runs in the browser, right inside the ELN you already use.
