Extraction Protocol Version Control (CRO / Contract)
Git-style version control for extraction protocols — track every revision, change summary, author and sign-off, tuned for a contract research organisation. Private and offline.
Keep an immutable, dated history of every extraction protocol — each version records what changed, who changed it and its sign-off status. Built for analytical labs who need client-traceable versions per study. Nothing leaves your browser, so even unpublished methods stay confidential.
Tip: bump the minor version (v1.1 → v1.2) for small edits and the major version (v2.0) for changes that affect results. Export to CSV for your QMS or an audit.
Indicative planning tool for research operations. Figures are estimates — verify lot data, expiry, calibration and budgets against the original certificates, vendor documentation and your institution's policies.
Free extraction protocol version control and change-log for a contract research organisation: track revisions, sign-offs and an audit trail entirely in your browser.
About Extraction Protocol Version Control (CRO / Contract)
A free, offline extraction protocol version-control tool for analytical labs. Keep an immutable, dated history of every extraction protocol — each version records what changed, who changed it and its sign-off status. Built for analytical labs who need client-traceable versions per study. Nothing leaves your browser, so even unpublished methods stay confidential.
How to use Extraction Protocol Version Control (CRO / Contract)
- 1Add v1.0 of your extraction protocol with a short description of the method (e.g. a solid-phase or solvent extraction).
- 2Each time you change it, log a new version with a change summary, your name and the date — never overwrite the old one.
- 3Set the status as it moves through Draft / Sponsor review / Approved / Locked / Amended, and export the full history to CSV for your records or QMS.
Why use Extraction Protocol Version Control (CRO / Contract)?
- ✓Extraction Protocols evolve constantly — this gives analytical labs a Git-style history so you always know which version produced which result.
- ✓Each entry captures a change summary, author, date and sign-off status (Draft → Sponsor review → Approved…), giving a contract research organisation client-traceable versions per study.
- ✓Runs entirely in your browser with no account — unpublished protocols and IP never touch a server.
Frequently asked questions
Why use version control for a extraction protocol?+
Methods drift over time, and a result is only reproducible if you know exactly which version of the extraction protocol produced it. Version control gives every revision a number, a change summary and an author, so you can reproduce old work, justify changes to reviewers, and onboard new analytical labs without losing institutional knowledge.
How should I number protocol versions?+
A simple semver-style scheme works well: bump the minor number (v1.1 → v1.2) for small edits like a reagent swap, and the major number (v1.x → v2.0) for changes that could affect results, such as a new incubation time or instrument. Record the rationale in the change summary so the jump is self-explanatory at audit.
Is this an electronic lab notebook (ELN)?+
It is a lightweight, offline version-control log rather than a full ELN — but it captures the part that matters most for reproducibility: a dated, attributable, immutable history of every change to a extraction protocol. You can export to CSV and attach it to your ELN or QMS at any time.
Where is my data stored?+
Entirely in your browser's localStorage — no sign-up, no upload, no server. That keeps proprietary methods and unpublished IP private and means the tool works offline, which is exactly what a contract research organisation needs.
