NYBB tissue block freezer box (SBB-box). The freezer box for tissue blocks holds 24 samples, stored in four columns with two rows (columns A and D) or 10 rows (columns B and C). The coordinate grids are printed on the outside of the box for columns (arrowhead) and for rows (arrow) to make retrieval of tissue easier. As samples are added and removed the bar code tags are scanned to confirm accurate placement and reduce errors. New samples are placed in the remaining spaces; the next slot to be filled in this box would be “B1”
