How Efficient is Your Lab? Part 4 - Maintaining Optimal Sample Quality During Transportation
Placing a cryogenic sample in dry ice is like dropping an ice cube into boiling water, a temperature differential of around 90°C, coupled with the enhanced convection and conductive when sample tubes are placed directly in contact with dry ice can cause sample temperature to rise quickly. The temperature differential between a cryogenic sample and dry ice is around 90°C.
To prevent enzymatic reactions cryopreserved samples should be kept lower than -130°C, this can be especially difficult during on site transport such as from a cryostore to a lab. This transport can often be done by putting cryogenic samples on dry ice during the short transport. It is them clear to see that during this transportation the temperature of cryogenic samples could rise rapidly, allowing for the breakdown of integrity due to enzymatic reactions.
