Temperature monitoring throughout transportation<br> The Hunan Provincial Cell and Tissue Bank employs a temperature control system throughout transportation. From the moment the sample is collected, the system is activated to accurately sense temperature changes to ensure temperature stability during transportation.<br> Guaranteed delivery within 36 hours<br> To preserve stem cell viability, Yuanpin Biotech arranges dedicated personnel and vehicles to ensure that samples are delivered to the laboratory within 36 hours.

Ensures the uniqueness and traceability of each stem cell sample.

Strict quality tests are required before cell collection and preparation, and before and during cell storage. Complete test parameters include pathogenic microorganisms, endotoxins, cell properties, cell purity, cell number and viability, and cell safety and efficacy.
