Most manufacturers’ tubes will not be pressure tested for ability to withstand leaks at 95 kPA (14psi). They may work, but have not been tested and verified in these conditions. Corning's products with plug seal caps are an example of one that is verified to ASTM standards.

Most transport tubes are not suitable for testing at <-70°C for long periods due to their thinner tube walls and butyl seal, if any seal at all. A true cryovial - with its thicker walls and silicon or TPE seals - will withstand the potentially deleterious effects of cold storage.
