When your lab runs through dozens of cryoboxes a month and the budget doesn't stretch to polycarbonate for every application, cardboard cryogenic boxes offer reliable cold storage at a fraction of the cost. The Heathrow Scientific Cardboard Cryogenic Tube Storage Box (50 mm height) holds standard 1.5 mL and 2.0 mL cryovials in a traditional 5.2 × 5.2-inch footprint that fits every standard upright and chest freezer rack designed for 2-inch boxes. The coated cardboard resists moisture penetration during normal freezer use, and the separate lift-off lid seats firmly to prevent accidental opening. Sold in economical 12-packs and available in White, Blue, Red, or an Assorted color mix, these boxes are the workhorse choice for high-volume labs that need affordable, disposable cryogenic storage.
Features and Benefits
Cost-Effective Cardboard Construction: Significantly lower per-box cost than polypropylene or polycarbonate alternatives — ideal for labs consuming large volumes of cryoboxes as disposable storage.
50 mm (2-Inch) Height: Standard 2-inch profile fits all upright and chest freezer racks designed for 2-inch cryoboxes, ensuring universal rack compatibility.
Moisture-Resistant Coating: Coated cardboard withstands the humidity inside freezers during normal storage cycles, preventing premature box degradation.
Separate Lift-Off Lid: Full-coverage lid seats securely on the box body, protecting contents from frost accumulation and cross-contamination.
12-Pack Economy: Sold in packs of 12 for bulk purchasing efficiency — stock up once and have boxes on hand for months of sample archiving.
Color Options: White for general use, Blue and Red for color-coded organization, or Assorted (Blue, Red, Yellow) for multi-project labs that need instant visual differentiation.

Laboratory Applications
High-volume biobanking and clinical sample archiving where hundreds of boxes are consumed annually and disposable storage keeps costs manageable
Teaching and educational laboratories where boxes may be discarded after a semester and reusable plastic containers are not cost-justified
Temporary project-based storage where samples are archived for a defined period and then discarded along with the container
Backup and overflow freezer storage when the lab's primary reusable cryobox inventory is fully allocated
Frequently Asked Questions
Do these boxes come with dividers/inserts?
No. The boxes ship as box-and-lid sets only. Cardboard dividers in 49-well, 64-well, 81-well, and 100-well configurations are sold separately — search for Heathrow cryogenic freezer box dividers to find the matching insert for your tube size.
How long do cardboard cryoboxes last in a −80 °C freezer?
With the moisture-resistant coating, these boxes typically last 1–2 years in a standard −80 °C mechanical freezer under normal access frequency. Heavily accessed boxes in frost-free freezers with frequent door openings may show wear sooner.
Can I write directly on the box?
Yes. The coated cardboard surface accepts permanent marker, lab pen, and adhesive labels. For best results at low temperatures, use cryo-rated labels or a solvent-resistant marker.
