Yes. We keep continuous temperature-monitoring networks, calibrated sensors, and 24/7 alarm escalation running for mechanical freezers, ultra-low -80 C units, and vapor-phase liquid nitrogen storage. Alarms reach the right people fast, even after hours and on weekends when no staff are on site, so excursions are caught before irreplaceable tissue is lost. Monitoring data is stored securely and kept audit-ready to satisfy CGTP and accreditation expectations for validated, documented cold-chain control. We also design the network and power resilience so the monitoring itself does not go dark during outages. Protecting grafts starts with never losing sight of the freezers that hold them.
