PolarSafe™ Metal Freezer Boxes are available in stainless steel or aluminum formats

Both the stainless steel and aluminum metal freezer boxes are guaranteed not to rust. They can be used in most liquid nitrogen tanks available on the market.

Drain holes in each box make them ideal for storing in liquid nitrogen vapor environments. Boxes are available in two sizes, with the option of 2" or 3" box heights. Metal boxes can be stored in the same rack configurations as 2" or 3" cardboard boxes. Cardboard dividers can be added depending on the application.
