Synopsis
See how telemetry, validated packaging, and receiving checklists keep fragile peptides inside their stability window.
Peptides are small, delicate sequences that unravel when they spend even an hour outside their temperature window. Cold chain execution is therefore a scientific control—not a shipping upgrade.
Temperature zones we live by
- 2–8°C: Short-term storage for most lyophilized lots.
- -20°C: Long-term hold for routine research peptides.
- -80°C: Reserved for highly labile analogs and reference standards.
The BioEdge playbook
- Each parcel carries a calibrated temperature logger streaming to our ops dashboard.
- Phase-change materials keep the internal cavity at the requested set point for 72+ hours.
- Excursion alerts trigger escalation long before the shipment reaches your loading dock.
- Every shipment includes a PDF of the temperature trace plus the COA QR code.
What failures look like
| Excursion type | Likely impact | Corrective action |
|---|---|---|
| Short warm spike (<2 hrs) | Possible aggregation | Quarantine lot, rerun HPLC/LC-MS |
| Prolonged heat (>8 hrs) | Loss of activity | Destroy lot, repeat synthesis |
| Freeze below spec | Container fractures, vial stress | Inspect packaging, requalify supplier |
Receiving checklist for your lab
- Document the condition of the shipper before opening.
- Verify indicator strips and compare to the telemetry report.
- Stage the vials directly into pre-cooled storage.
- Save the PDF trace with your study records for audit readiness.
Cold chain rigor is how we convert syntheses into reliable research fuel. When the temperature story is transparent, you can trust the biology you observe.
