Corrugated Polypropylene Freezer Box

Laboratory freezers represent the most critical footprint in a research facility, and utilizing bulky or rapidly degrading cardboard boxes compromises both storage density and sample safety. The Heathrow Scientific Corrugated Polypropylene Cryogenic Freezer Box provides a highly durable, sustainable alternative to cardboard that resists moisture and withstands repeated freeze-thaw cycles without breaking down.

Manufactured from robust corrugated polypropylene, these boxes safely secure samples down to -80°C in mechanical ultra-low freezers. To maximize your incoming inventory space, they arrive completely flat-packed and assemble effortlessly. With multiple configurations available—ranging from 144-place microtube boxes to 16-place 50mL conical boxes—you can standardize your entire freezer architecture on one reliable material.

Features and Benefits

Moisture Resistant: Corrugated plastic repels condensation and prevents the mold growth commonly seen with degrading cardboard.
Deep Freeze Rated: Specifically engineered to remain stable during repeated thermal cycling down to -80°C.
Flat-Packed Delivery: Drastically reduces incoming shipping volume and necessary stockroom shelf space.
Comprehensive Formats: Available in exact dimensions for 0.2mL, 0.5mL, 1.5/2.0mL, 15mL conicals, 50mL conicals, and squat vials.
Included Dividers: Every box includes properly sized, pre-assembled dividers for immediate use.

Frequently Asked Questions

Will these fit in standard freezer racks?
Yes, the 81-place and 100-place boxes utilize standard 5.2 x 5.2 inch footprints (or similar universal sizing) to easily slide into standard stainless steel freezer racking systems.

Are the dividers built-in or removable?
The pre-assembled corrugated dividers are dropped into the box and can be removed if you need an open-format storage bin.

Can these go in liquid nitrogen?
These are rated safely down to -80°C. For vapor phase liquid nitrogen, they can be utilized, but direct submersion is not recommended.
