Choosing the right dry shipper depends on what you’re transporting and how long it needs to remain at cryogenic temperature. Each model has a specific capacity, usually defined by how many vials, straws, or canisters it can safely hold, as well as how long it can maintain temperatures below –150°C.
If you’re sending a small number of samples or require something lightweight for air freight, a compact dry shipper is usually sufficient. For larger sample volumes or longer transport times, opt for a model with greater liquid nitrogen capacity and longer static hold time. Always check the manufacturer’s details for hold time, working duration, and absorption capacity, as these determine how long your samples remain stable.
It’s also important to ensure compatibility with your existing racks, visotubes, or storage straws, since internal dimensions can vary between brands. In short, match the model to your sample type, shipping distance, and handling needs choosing one that provides enough capacity and duration without adding unnecessary weight or bulk.
