Cryo-Stock Expiry Tracker (Teaching Lab)
Track cryo-stock lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for a teaching or undergraduate teaching lab. 100% in your browser.
Log every cryo-stock with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so biobanks and cell-line repositories use the right stock first and waste nothing. Default shelf-life ≈ 10.0 year(s); stored LN₂ vapour phase −150 °C. Designed to prevent lost viability from a tank that ran low on liquid nitrogen.
Default shelf-life for this category ≈ 3650 days from manufacture. Items within 0 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 cryo-stock expiry tracker with FEFO ordering and reorder alerts for a teaching or undergraduate teaching lab — runs offline, no sign-up.
About Cryo-Stock Expiry Tracker (Teaching Lab)
Sized for teaching labs running scheduled practicals: plan reagents per class, flag what expires before the next cohort. Log every cryo-stock with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so biobanks and cell-line repositories use the right stock first and waste nothing. Default shelf-life ≈ 10.0 year(s); stored LN₂ vapour phase −150 °C. Designed to prevent lost viability from a tank that ran low on liquid nitrogen.
How to use Cryo-Stock Expiry Tracker (Teaching Lab)
- 1Add each cryo-stock: name, lot/catalog number, quantity in vials, and the printed expiry date.
- 2Watch the FEFO strip — items within 0 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 Cryo-Stock Expiry Tracker (Teaching Lab)?
- ✓Used by biobanks and cell-line repositories to stop stock expiring unnoticed and to keep cryo-stock purchasing predictable.
- ✓FEFO ordering surfaces the next cryo-stock to use, and the 0-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 cryo-stocks?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For cryo-stocks this avoids lost viability from a tank that ran low on liquid nitrogen, 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 cryo-stocks typically last, and how should they be stored?+
Unopened, a cryo-stock commonly carries about 10.0 year(s) of shelf-life, stored LN₂ vapour phase −150 °C. 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 0 days. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
