Chemical Expiry Tracker
Track chemical lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for an academic research lab. 100% in your browser.
Log every chemical with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so synthetic chemistry and EHS teams use the right stock first and waste nothing. Default shelf-life ≈ 3.0 year(s); stored per SDS — see hazard class. Designed to prevent peroxide-forming ethers stored past their safe limit.
Default shelf-life for this category ≈ 1095 days from manufacture. Items within 90 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.
Free chemical expiry tracker with FEFO ordering and reorder alerts for an academic research lab — runs offline, no sign-up.

- 3Export the list to CSV any time for ordering, audits or handover; nothing is uploaded.
Why use Chemical Expiry Tracker?
- ✓Used by synthetic chemistry and EHS teams to stop stock expiring unnoticed and to keep chemical purchasing predictable.
- ✓FEFO ordering surfaces the next chemical to use, and the 90-day alert gives time to reorder before a gap.
- ✓Runs entirely offline in your browser — sensitive lot and supplier data never touches a server.
Frequently asked questions
What is FEFO and why does it matter for chemicals?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For chemicals this avoids peroxide-forming ethers stored past their safe limit, 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 chemicals typically last, and how should they be stored?+
Unopened, a chemical commonly carries about 3.0 year(s) of shelf-life, stored per SDS — see hazard class. 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 research environments require, and it means the tool keeps working with no internet.
Can I use this for an academic research lab?+
Yes — this variant is tuned for an academic research lab: the reorder alert is set to 90 days. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
