Phoenix ELN
Phoenix ELN is a free, open-source electronic lab notebook for Windows, suited to organic, organometallic, and peptide chemistry.
What Phoenix ELN is
Phoenix ELN is a free, open-source electronic lab notebook for Windows, suited to organic, organometallic, and peptide chemistry. Its experiment protocols can arrange reactants, reagents, solvents, comments, products, images, and files in workflow order. When materials are added, the application provides stoichiometric details such as equivalents and millimoles. A built-in, self-learning materials database includes nearly 200 commonly used reagents, solvents, and auxiliaries, with cross-checked molecular weights and densities. The integrated drawing editor supports organic, organometallic, peptide, and resin-bound structures. Users can search reaction substructures in local experiments; an optional in-house server adds searches across finalized experiments in an organization. Phoenix ELN works without a server connection and supports offline access. The optional server also provides continuous backup and experiment sharing, and its package includes an installation script for MySQL or MariaDB. Protocols can be exported as PDF compliant with PDF/A-3b, with inserted documents embedded as PDF attachments. Other listed export formats are ZIP, JPEG, PNG, and TIF. The maker directs bug reports, suggestions, and questions to GitHub Issues and Discussions; ChemBytes support is for commercial software only.
Good
- Free and open source.
- Works offline without a server connection.
- Calculates equivalents and millimoles for added materials.
- Supports local reaction substructure searches.
- Exports protocols as PDF/A-3b.
Watch out
- Windows is the stated target platform.
- Organization-wide searches require the optional server.
- ChemBytes support is for commercial software only.
Who it suits
Phoenix ELN is aimed at chemistry researchers working with organic, organometallic, or peptide experiments. It may suit users who want an offline notebook and can manage an optional in-house server for shared workflows.
Verdict
Phoenix ELN offers chemistry-specific protocol organization, calculations, and local search at no cost. Consider the Windows target and optional server requirements if you need organization-wide sharing and searches.
