FFPE Block Chain of Custody
Log every FFPE block handoff — released-by, received-by, time, condition and location — for a research biobank. Builds an exportable, time-stamped custody chain, 100% offline.
Record every transfer of a FFPE block — who released it, who received it, when, the storage condition (RT, dust-free drawer) and the location. Built for pathology archives who need an exportable, time-stamped custody chain. Each handoff is an immutable row you can export to CSV; nothing leaves your browser.
Every transfer should be recorded as soon as it happens. A gap in the chain weakens the record, so log received-by and condition at the moment of handoff. Export to CSV for your LIMS, auditor or case file.
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 FFPE block chain-of-custody log for a research biobank: time-stamped handoffs, condition and location, exportable to CSV — entirely offline.
About FFPE Block Chain of Custody
A free, offline chain-of-custody log for pathology archives. Record every transfer of a FFPE block — who released it, who received it, when, the storage condition (RT, dust-free drawer) and the location. Built for pathology archives who need an exportable, time-stamped custody chain. Each handoff is an immutable row you can export to CSV; nothing leaves your browser.
How to use FFPE Block Chain of Custody
- 1When a FFPE block is collected or received, add the first custody row with its ID/barcode and the receiver's name.
- 2Log a new row at every handoff — release, transport, aliquoting, analysis or disposal — with the date-time and condition.
- 3Export the full chain to CSV any time for your LIMS, an audit, or a case file. The records never leave your device until you export them.
Why use FFPE Block Chain of Custody?
- ✓Maintains an unbroken custody trail for every FFPE block, so pathology archives can prove who held the sample, when and in what condition.
- ✓Captures release/receipt, date-time, storage condition (RT, dust-free drawer) and location — the fields a research biobank needs for an exportable, time-stamped custody chain.
- ✓Offline-first and private — sensitive specimen and donor data is stored only in your browser, never uploaded.
Frequently asked questions
What is a chain of custody for a FFPE block?+
A chain of custody is the chronological, documented record of everyone who handled a FFPE block from collection to disposal — each transfer recording who released it, who received it, when, and the storage condition. An unbroken chain is what lets pathology archives (and any reviewer) trust that the sample's identity and integrity were preserved.
Why does specimen condition matter in the custody record?+
Because integrity depends on it. A FFPE block should be kept RT, dust-free drawer; if a transfer breaks that — a warm freezer, an exceeded holding time — the result may be invalid. Recording condition at each handoff makes any excursion visible and defensible, and is exactly what accreditation reviewers and courts look for.
Is this suitable for a research biobank?+
Yes — this variant is framed for a research biobank and aims to produce an exportable, time-stamped custody chain. It complements your LIMS or accreditation paperwork; export to CSV to file it formally.
Where is the custody data stored?+
Only in your browser, via localStorage — no account, no upload, no third-party server. That keeps donor, patient and case data private and lets the tool work offline in the lab. Export to CSV whenever you need a permanent or shareable copy.
