A “standard” box is made from cardboard, plastic, stainless steel or aluminum.  The outside dimensions of standard cardboard and plastic boxes are 5 ¼” x 5 ¼”.  The outside dimensions for stainless steel and aluminum boxes are 5” x 5”.  Standard size boxes are primarily made to hold cryogenic vials.  Eighty-one (81) of the 1.0 mL and 2.0 mL vials will fit into 2-inch high standard boxes.  Eighty-one (81) of the 4.0 mL and 5.0 mL vials will fit into 3-inch high standard boxes.  The 5.0 mL vial will raise the lid of a standard 3-inch high cardboard box to 3.75-inches.  There is also a standard size plastic box that is tall enough to accommodate a 5.0 mL vial.  Standard plastic boxes can hold (81) or (100) vials depending on the caps on the vials.

Vials have different types of caps.  With an external thread on the vial, the cap will be larger than the vial body and will require more room for storage.  The externally threaded vials will require 81-cell dividers.  Vials with internal threads have the same body and cap size and will fit into a 100-cell divider.

Custom Biogenic Systems makes cell dividers for a number of sizes other than the most popular 81-cell and 100-cell sizes.  Visit CBSfreezerracks: DIVIDERS to view our complete line of cell dividers
