Temperature Controlled Courier

Containers
We supply containers for routine ranges. Specialized and validated packaging is typically client-provided, and we manage client loggers under your return protocol. Passive containers are qualified against defined hold times.
Where a transit would exceed qualified hold time for a range, we say so before accepting the job rather than after.

Excursion Handling
Notify origin and destination within 30 minutes. The client decides the disposition. A written report with logger data follows within 24 hours, with corrective action reviewed within three business days and records retained seven years.

What We Need From You
- Required range and tolerance
- Maximum permissible transit time
- Container type and who supplies it
- Logger type and return protocol
- Excursion escalation contact and threshold
- Quarantine instruction on excursion.
