81-place cardboard freezer storage boxes have liquid-resistant coating, attached, hinged, flip top lids, include pre-inserted 81-place dividers and come available in various colors.
81 place cardboard freezer boxes are good for use with 0.5 mL, 1.5 mL and 2.0 mL minicentrifuge tubes and 1 mL to 2 mL (e.g. 1.8 mL) internally- and externally-threaded cryovials.
81-place boxes are recommended for externally-threaded 1 mL to 2 mL cryovials, as some externally-threaded cryovials are a little too wide to fit well into 100-place boxes, which are available for purchase here.
MTC Bio FlipTop™ cardboard freezer storage boxes are made of recycled cardboard, have drain holes in the bottoms of the boxes and alpha-numeric coding on the tops, sides and insides for easy sample identification.
Cardboard freezer storage boxes hold 81 tubes (9 tubes x 9 tubes format) and measure 5 ¼ x 5 ¼ x 2 inches so that they fit into standard freezer storage and liquid nitrogen racks.
Fiberboard freezer storage boxes come 5 boxes/pack or 50 boxes/case and are available in the following colors: Red, Purple, Orange, Green, Blue, White and in Assorted Colors (select in dropdown menu).
