Heathrow Scientific Cardboard Cryogenic Storage Box 75mm - HS2860B | Tall-Format, Pack of 12

Tall cryogenic vials and larger tube formats don't fit in standard 2-inch cryoboxes, leaving labs scrambling for ad-hoc storage solutions that waste freezer space. The Heathrow Scientific Cardboard Cryogenic Tube Storage Box in the 75 mm (3-inch) height accommodates taller vials, 3–5 mL cryotubes, and other extended-length containers that overshoot the 50 mm box limit. The coated white cardboard resists moisture in freezer environments, and the lift-off lid provides full top access for loading and retrieving tubes. At just $26.00 per pack of 12, these boxes deliver the same economical, disposable-friendly storage philosophy as the 50 mm version — scaled up for larger tube inventories.

Features and Benefits

• 75 mm (3-Inch) Height: Accommodates taller cryogenic vials, 3–5 mL cryotubes, and extended-length sample containers that do not fit standard 50 mm (2-inch) cryoboxes.

• Economical Cardboard Construction: Coated cardboard at a fraction of the cost of plastic alternatives — ideal for high-volume labs that treat cryoboxes as disposable consumables.

• Moisture-Resistant Coating: Withstands the humidity inside −80 °C freezers during typical storage durations without softening or structural failure.

• Standard Cryobox Footprint: The 5.2 × 5.2-inch base fits all freezer racks designed for standard 3-inch (75 mm) cryoboxes.

• 12-Pack Value: Bulk 12-pack packaging keeps per-unit cost low and ensures boxes are always on hand when new sample sets arrive.

Specifications

Laboratory Applications

• Archival storage of tall-format cryogenic vials (3–5 mL) that exceed the 50 mm height limit of standard 2-inch cryoboxes

• Freezer organization in veterinary, environmental, and food-safety labs that routinely collect larger sample volumes requiring taller containers

• Temporary overflow storage when incoming sample batches exceed the capacity of existing reusable 3-inch plastic cryoboxes

Frequently Asked Questions

What is the difference between the 50 mm and 75 mm cardboard boxes?
The only difference is height: 50 mm (2 in) versus 75 mm (3 in). The base footprint (5.2 × 5.2 in) is identical, so both fit the same freezer rack column — just different shelf heights.

Do dividers come included?
No. Cardboard dividers for various well counts (49, 64, 81, 100) are sold separately. For 15 mL and 50 mL tube dividers, see the Heathrow cardboard partition/divider listings.

Can I use these in a liquid-nitrogen freezer?
Cardboard boxes are not recommended for liquid-nitrogen immersion or vapor-phase LN₂ storage. For LN₂ environments, use polycarbonate cryoboxes such as the Heathrow Arctic Squares® line.
