Primer Expiry Tracker (Teaching Lab)
Track primer lots, quantities and expiry with FEFO ordering and reorder alerts — tuned for a teaching or undergraduate teaching lab. 100% in your browser.
Log every primer with its lot, quantity and expiry; the list reorders by soonest-to-expire (FEFO) so PCR, qPCR and sequencing labs use the right stock first and waste nothing. Default shelf-life ≈ 1.0 year(s); stored −20 °C lyophilized or in TE. Designed to prevent degradation of resuspended oligos left at 4 °C too long.
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 primer expiry tracker with FEFO ordering and reorder alerts for a teaching or undergraduate teaching lab — runs offline, no sign-up.
About Primer Expiry Tracker (Teaching Lab)
Sized for teaching labs running scheduled practicals: plan reagents per class, flag what expires before the next cohort.

How to use Primer Expiry Tracker (Teaching Lab)
- 1Add each primer: name, lot/catalog number, quantity in tubes, and the printed expiry date.
- 2Watch the FEFO strip — items within 30 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 Primer Expiry Tracker (Teaching Lab)?
- ✓Used by PCR, qPCR and sequencing labs to stop stock expiring unnoticed and to keep primer purchasing predictable.
- ✓FEFO ordering surfaces the next primer to use, and the 30-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 primers?+
FEFO means First-Expired-First-Out: you consume the stock with the nearest expiry before newer stock, regardless of when it arrived. For primers this avoids degradation of resuspended oligos left at 4 °C 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 primers typically last, and how should they be stored?+
Unopened, a primer commonly carries about 1.0 year(s) of shelf-life, stored −20 °C lyophilized or in TE. 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.
