Cold Chain Transportation Technology

● Temperature monitoring throughout transportation

The Hunan Provincial Cell and Tissue Bank employs a temperature monitoring system throughout transportation. From the moment of sample collection, the system is activated to accurately sense temperature changes to ensure temperature stability during transportation.

● Guaranteed delivery within 36 hours

To preserve stem cell viability, the company arranges dedicated personnel and vehicles to ensure that the collected samples are delivered to the laboratory within 36 hours.

Unique Coding and Identification System

Ensures the uniqueness and traceability of each cell sample produced and prepared.

Comprehensive Quality Testing

Strict quality tests are required before sample collection (clinical examination by medical institutions), before cell preparation, before and during cell storage, and before the release of cell formulations. Complete test parameters include pathogenic microorganisms, endotoxins, cell properties, cell purity, cell number and viability, and cell safety and efficacy.
