Cardboard Boxes
Various hinged or non-hinged cardboard storage boxes are available to carefully store sample tubes, centrifuge tubes, and cryogenic vials stored in mechanical -80 freezers or LN2 storage equipment. Removable dividers, tubes, and vials are sold separately. Due to extreme temperature conditions and the freezing/thawing effect, waterproof options are available.  Specs vary; make sure to verify all measurements.
