Stain / Dye Expiry Tracker (Core Facility)
Track stain / dye lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for a shared core facility serving many groups. 100% in your browser.
Log every stain / dye with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so histology and microscopy labs use the right stock first and waste nothing. Default shelf-life ≈ 2.0 year(s); stored RT or 4 °C, dark. Designed to prevent fluorophore photobleaching from light exposure in storage.
Default shelf-life for this category ≈ 730 days from manufacture. Items within 59 days of expiry are flagged.
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.

Frequently asked questions
What is FEFO and why does it matter for stain / dyes?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For stain / dyes this avoids fluorophore photobleaching from light exposure in storage, cuts waste and keeps results consistent. This tracker sorts every entry by expiry automatically so the next item to use is always at the top.
How long do stain / dyes typically last, and how should they be stored?+
Unopened, a stain / dye commonly carries about 2.0 year(s) of shelf-life, stored RT or 4 °C, dark. Always defer to the lot-specific expiry on the certificate or label — manufacturer dating accounts for the exact formulation and is what an auditor will check.
Is my inventory data private?+
Yes. Everything is stored locally in your browser using localStorage — no account, no upload, no server. That offline-first design is exactly what institutional IT and sensitive clinical/GMP environments require, and it means the tool keeps working with no internet.
Can I use this for a shared core facility serving many groups?+
Yes — this variant is tuned for a shared core facility serving many groups: the reorder alert is set to 59 days and an audit/CoA reference column is included for traceability. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
