Phoenix ELN

What Phoenix ELN is
Phoenix ELN is an open-source electronic lab notebook for organic, organometallic, and peptide chemistry. It runs on Windows and works offline without a server connection. Experiment protocols can arrange reactants, reagents, solvents, comments, products, images, and files in workflow order. As materials are added, the application supplies stoichiometric information such as equivalents and millimoles. Its built-in self-learning materials database contains nearly 200 commonly used reagents, solvents, and auxiliaries, with cross-checked molecular weights and densities. An integrated drawing editor supports organic, organometallic, peptide, and resin-bound structures. Users can search reaction substructures in local experiments; an optional in-house server extends searches to finalized experiments across an organization and supports experiment sharing and continuous backup. Protocols export to PDF compliant with PDF/A-3b, with inserted documents embedded as PDF attachments. Other listed export formats are ZIP, JPEG, PNG, and TIF. The optional server package includes an installation script for MySQL or MariaDB.
Who it suits
It suits chemistry researchers who want an offline notebook for organizing protocols and reaction structures. Teams can add the optional server for shared experiments, backups, and organization-wide searches.
What it does well
- Works without a server connection and supports offline access
- Includes nearly 200 common materials
- Calculates equivalents and millimoles as materials are added
- Exports protocols to PDF/A-3b-compliant PDF
What to know first
- The identified target platform is Windows
- Organization-wide searches require the optional server
Limits
The free plan is available at no cost to end users. Organization-wide reaction searches, experiment sharing and continuous backup are provided by the optional server.
