Calibration Gas Cylinder Expiry Tracker
Track calibration gas cylinder lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for an academic research lab. 100% in your browser.
Log every calibration gas cylinder with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so instrument and environmental labs use the right stock first and waste nothing. Default shelf-life ≈ 2.0 year(s); stored secured, upright, ventilated. Designed to prevent the certified mixture expiring while still under pressure.
Default shelf-life for this category ≈ 730 days from manufacture. Items within 60 days of expiry are flagged.
Indicative guidance only. Always follow the manufacturer's Safety Data Sheet (SDS) and your institution's chemical hygiene plan. The SDS and your EHS officer have the final word on handling, storage and disposal.

Frequently asked questions
What is FEFO and why does it matter for calibration gas cylinders?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For calibration gas cylinders this avoids the certified mixture expiring while still under pressure, 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 calibration gas cylinders typically last, and how should they be stored?+
Unopened, a calibration gas cylinder commonly carries about 2.0 year(s) of shelf-life, stored secured, upright, ventilated. 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 60 days. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
