Containment of Cold Materials

There are two concerns for the storage of cold materials longevity of the material and safety to the user. For example, if you place an ice cube on a lab bench, it will melt. On the other hand, if you place an ice cube in an insulated container, it will also melt—but it will take longer. By providing insulation, you have added to the ice cube s longevity. If you hold an ice cube for an extended time, your hands will soon become so cold that eventually you will need to drop the ice cube. However, if you hold an insulated container containing an ice cube, there is no discomfort. 

Cost of coolant. If the coolant is inexpensive and readily available, you don t need a highly efficient container. 

Use of the container. Will the container be stationary most of the time 

The handling abilities of the user. Is the user clumsy or careful  

The operational use of the coolant. Will the coolant need to be left
