Divided Specimen Trays measure 14 x 22 x 2. These are oversize, fold-up self-locking trays made entirely of acid-free, lignin- free, corrugated board. They use neither glue nor metal corners. These trays can accommodate three dividers in either dimension but you can’t use both long and short dividers in the same box. Choose dividers for either the short or the long dimension when your order. Quantities may be combined for price breaks. Available in MicroChamber and MicroChamber/ Silversafe corrugated boards.
