Economical cryovial boxes fit all liquid nitrogen and mechanical square or upright storage racks. Select a box and partition that fit the size and number of vials for your needs. Two box sizes (lids included) are available, as well as 100-, 81-, 64- and 49-cell partitions that fit in either box. Colored cardboard boxes are ideal for identification and sorting purposes. Choose between blue, red, yellow or assorted (four each of blue, red, and yellow). Both the boxes and the partitions sell in packs of 12.
