Why is it called "Isothermal", and what makes it special?

CBS "Isothermal" liquid nitrogen vapor storage systems allow frozen sample storage at liquid nitrogen temperatures without liquid nitrogen contact. This innovative design provides storage temperatures in the -190°C range with absolutely no liquid nitrogen in the sample storage space. This PATENTED system totally eliminates the need to submerge any type of sample in liquid nitrogen. (If you don't know why you should keep your samples away from liquid phase read this.)

As shown in this picture graphic, the liquid nitrogen is held in a jacket that surrounds the dry sample storage space. This means that the cryogenic temperature is virtually the same from bottom to top, unlike a standard freezer that must have a shallow pool at the bottom of the space for cooling.

Of course, that shallow pool in a standard freezer takes away 3-4 levels of potential storage space, so for the same footprint you might get 35% more storage capacity with and Isothermal Freezer.
