Dewar generally refers to a smaller, often portable, vacuum-insulated vessel, while cryogenic tank is more commonly used for larger, fixed bulk storage installations, though in everyday use across the industry the two terms overlap considerably. What actually matters when specifying equipment is not the label but the intended use: static sample storage, bulk liquid nitrogen holding, or portable transport between sites each call for different design priorities around vacuum life, capacity and handling. Cryolab’s range covers this spectrum, from our CryoStork dry shippers designed for safe transport of biological samples, through to our CryoNest storage vessels for fixed laboratory storage.
