Reference Standard Expiry Tracker (Teaching Lab)
Track reference standard lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for a teaching or undergraduate teaching lab. 100% in your browser.
Log every reference standard with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so analytical chemistry and QC labs use the right stock first and waste nothing. Default shelf-life ≈ 3.0 year(s); stored per certificate. Designed to prevent certified value lapsing, voiding traceable calibration.
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.

Frequently asked questions
What is FEFO and why does it matter for reference standards?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For reference standards this avoids certified value lapsing, voiding traceable calibration, 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 reference standards typically last, and how should they be stored?+
Unopened, a reference standard commonly carries about 3.0 year(s) of shelf-life, stored per certificate. 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 a teaching or undergraduate teaching lab?+
Yes — this variant is tuned for a teaching or undergraduate teaching 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.
