81-Position Cardboard Freezer Storage Boxes for 0.4 mL CryoSure® Vials — White, 12/Bag (240-8281-000)
These 81-position cardboard freezer storage boxes are purpose-built to organize and archive 0.4 mL CryoSure® cryo vials (Caplugs® Evergreen 300-3900 family) across the full cryogenic temperature range, from standard -20°C and -80°C freezers through liquid nitrogen vapor phase storage at -196°C. The 9×9 grid layout delivers 81 individually addressed positions per box — significantly more specimens per box than standard 50-position formats — supporting high-density biobank, pharmaceutical, and research specimen archiving without proportionally increasing freezer drawer footprint. Supplied non-sterile in bags of 12, these white cardboard boxes ship ready for immediate integration into cryo storage programs.

Compatibility
These storage boxes are designed as the matched companion box for the Caplugs® Evergreen 300-3900 CryoSure® 0.4 mL cryo vial family, enabling complete vial-and-box procurement from a single authorized vendor. Compatible color-coded CryoSure® vial options include 300-3900-G20 (Green, 200/Bag), 300-3900-R20 (Red, 200/Bag), and 300-3900-Y20 (Yellow, 200/Bag), supporting color-coded aliquot management schemes. Laboratories using other brands of 0.25–0.5 mL cryogenic vials should verify vial outer diameter against the well dimensions before placing a bulk order to confirm fit.

Frequently Asked Questions
What vials are these boxes designed for?
They are purpose-built for 0.4 mL CryoSure® cryo vials from the Caplugs® Evergreen 300-3900 family. Laboratories using other 0.25–0.5 mL cryogenic vial formats should confirm their vial's outer diameter matches the well dimensions before ordering in bulk.
Are these boxes rated for liquid nitrogen storage?
Yes — in addition to standard -20°C and -80°C mechanical freezers, these boxes are rated for liquid nitrogen vapor phase storage at -196°C, making them suitable for the most demanding long-term cryopreservation programs.
Can I write directly on the boxes for labeling?
Yes — the white cardboard surface accepts permanent marker for box-level identification and individual row-column position labeling, supporting chain-of-custody workflows and LIS-linked specimen tracking systems.
Are these boxes supplied sterile?
No — they are supplied non-sterile. For most cryo archiving and biobank applications, sterility of the storage box itself is not required, as vials are sealed prior to placement. If sterile storage consumables are required for your workflow, please contact LabSupplies.com for guidance.
