Competent-Cell Aliquot Expiry Tracker (Teaching Lab)
Track competent-cell aliquot lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for a teaching or undergraduate teaching lab. 100% in your browser.
Log every competent-cell aliquot with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so cloning and synthetic-biology labs use the right stock first and waste nothing. Default shelf-life ≈ 1.0 year(s); stored −80 °C, single use. Designed to prevent transformation efficiency collapse from a single warm-up.
Default shelf-life for this category ≈ 365 days from manufacture. Items within 30 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 competent-cell aliquot expiry tracker with FEFO ordering and reorder alerts for a teaching or undergraduate teaching lab — runs offline, no sign-up.

Frequently asked questions
What is FEFO and why does it matter for competent-cell aliquots?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For competent-cell aliquots this avoids transformation efficiency collapse from a single warm-up, 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 competent-cell aliquots typically last, and how should they be stored?+
Unopened, a competent-cell aliquot commonly carries about 1.0 year(s) of shelf-life, stored −80 °C, single use. 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 30 days. Add your own columns by adapting the entries, and export to CSV to feed your ordering or LIMS workflow.
