The 9×9 grid provides 81 individually addressed positions — 62% more specimens per box than a standard 50-position format — enabling high-density biobank and compound library archiving without proportionally increasing freezer drawer real estate. Each position is individually accessible for random-access specimen retrieval without disturbing adjacent vials — the defining operational requirement for large biorepository programs performing daily random-access sample retrieval.\u003c\/p\u003e \u003cp\u003eStandard laboratory cardboard construction provides dimensional stability across the full cryogenic temperature range from -20°C through -196°C liquid nitrogen vapor phase — the material of choice for cryo storage boxes across biobank, pharmaceutical, and research programs worldwide. Cardboard's low thermal mass enables rapid temperature equilibration during storage and retrieval cycles, minimizing the thermal stress on neighboring vials during individual specimen access. The white surface accepts permanent marker for box-level and row-column position labeling, supporting chain-of-custody and LIS-linked specimen tracking.\u003c\/p\u003e \u003cp\u003eAt $54.41 per 12\/Bag — $4.5339 per box — the delivers high-density cryo vial archiving at economics supporting single-use-per-aliquoting-event allocation in high-throughput biobank programs.
