Buffer Expiry Tracker
Track buffer lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for an academic research lab. 100% in your browser.
Log every buffer with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so biochemistry and analytical labs use the right stock first and waste nothing. Default shelf-life ≈ 0.49 year(s); stored 4 °C, check for precipitate. Designed to prevent microbial growth in unpreserved buffers stored too long.
Default shelf-life for this category ≈ 180 days from manufacture. Items within 21 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 buffer expiry tracker with FEFO ordering and reorder alerts for an academic research lab — runs offline, no sign-up.
About Buffer Expiry Tracker

How to use Buffer Expiry Tracker
- 1Add each buffer: name, lot/catalog number, quantity in bottles, and the printed expiry date.
- 2Watch the FEFO strip — items within 21 days of expiry are flagged so you can use or reorder them first.
- 3Export the list to CSV any time for ordering, audits or handover; nothing is uploaded.
Why use Buffer Expiry Tracker?
- ✓Used by biochemistry and analytical labs to stop stock expiring unnoticed and to keep buffer purchasing predictable.
- ✓FEFO ordering surfaces the next buffer to use, and the 21-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 buffers?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For buffers this avoids microbial growth in unpreserved buffers stored too long, 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 buffers typically last, and how should they be stored?+
Unopened, a buffer commonly carries about 0.49 year(s) of shelf-life, stored 4 °C, check for precipitate. 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 21 days. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
