Cardboard Freezer Box Partitions - Replacement Dividers - Heathrow Scientific

Torn or missing internal dividers render standard 5x5 inch cardboard freezer boxes useless, leading to disorganized samples and wasted storage space. Heathrow Scientific Cardboard Cryogenic Freezer Box Partitions allow you to quickly restore or re-configure your existing cryogenic boxes without replacing the entire outer shell.

Manufactured from durable, cold-resistant cardboard, these replacement dividers drop easily into standard cryogenic vial storage boxes. They are rated to withstand vapor phase liquid nitrogen temperatures down to -196°C. Available in multiple dense arrays (100, 81, 64, or 49 wells), they provide an economical way to customize your storage architecture based on changing sample dimensions.

Features and Benefits

• Direct Replacement: Perfectly sized to drop into standard 5 x 5 inch (13 x 13 cm) cardboard cryogenic storage boxes.

• Customizable Configurations: Choose from 100-well, 81-well, 64-well, or 49-well formats to precisely fit varying tube diameters.

• Deep Freeze Rated: Cardboard construction is stable down to -196°C for vapor phase nitrogen and -80°C mechanical freezers.

• Economical Solution: Saves budget by allowing researchers to refurbish intact boxes rather than purchasing completely new units.

Laboratory Applications

• Refurbishing heavily used cardboard boxes in -80°C biobanking freezers

• Re-configuring standard storage boxes to accept wider-diameter cryovials

• Organizing small microfuge tubes securely within deep cryogenic environments

Frequently Asked Questions

Are these shipped fully assembled?
Yes, the grids arrive pre-slotted and assembled. You simply drop them directly into your empty freezer box.

Do they fit boxes from other brands?
These partitions are built to standard dimensions and will fit most universal 5x5 inch (13x13 cm) cryogenic freezer boxes on the market.

Will the 100-well size hold standard 2.0mL tubes?
The 100-well format has a tighter 11.5mm diameter. Standard 1.5mL or internally-threaded cryovials fit well, but thicker, externally-threaded 2.0mL tubes generally require the 81-well (12mm) format.
