It is a delicate and sensitive affair to ship a cold chain considering the nature of the valuable materials as well as the samples. In most cases, people have to care about the overnight shipping, to buy and maintain dry ice, to pay charges for hazardous goods, to worry about the damage to the integrity of the cells and the sample, and to train the staff to meet the standards. Under normal circumstance, that was what it took to have your cold chain shipped, however, much has improved concerning technology, regulation, and management that have turned around the cold chain shipment business. Let us analyze some of the improvements that have revolutionized the entire process of cold chain shipping:

Improvements

Modern equipment

Long ago, the cold chain shipping firms used to buy dry ice to keep the temperature of the ship during the transit. Nevertheless, this method has proven unreliable and exposes the cell, and samples to risks associated with temperature excursions. Today, most advanced facilities use liquid nitrogen as the refrigerant in which case, the dry vapor shipper absorbs all the liquid nitrogen fully into porous foam inside the shipper.

Consequently, the carrier then can release the liquid nitrogen slowly inside the container to sustain the cryogenic temperature of more than -180°C making the temperature constant throughout the trip up to twenty-one days. It works better than other temperature control solutions for shipment such as dry ice thereby eliminating OD temperature excursions virtually.
