Mid-range cryovials and 5 mL tubes occupy an awkward middle ground — too large for microtube cryoboxes, too small to justify 50 mL tube containers. The Heathrow Scientific Corrugated Polypropylene Cryogenic Freezer Box for 5 mL Tubes provides a dedicated 25-place (5 × 5) grid with 22.6 mm wells sized precisely for 5 mL cryotubes and sample vials. Built from the same waterproof, flat-pack corrugated polypropylene as the microtube versions, this box resists moisture damage and mold while shipping economically in flat-packed cartons. Pre-assembled dividers are included, so each box is ready to load the moment you fold it into shape.
Features and Benefits
25-Place Grid (5 × 5): Each well is 22.6 mm in diameter — purpose-built for 5 mL cryotubes and sample vials that are too wide for standard microtube dividers.
Corrugated Polypropylene: Waterproof, mold-resistant, and reusable — outlasts cardboard boxes by an order of magnitude in humid freezer environments.
Flat-Pack with Pre-Assembled Dividers: Ships flat for efficient storage, pops into shape instantly, and includes fitted dividers — no separate purchase needed.
Rated to −80 °C: Reliable in ultra-low temperature mechanical freezers without embrittlement or deformation.
Standard Cryobox Footprint: 5.2 × 5.1-inch base fits standard freezer rack bays designed for 2-inch cryoboxes.

Laboratory Applications
Cryogenic storage of 5 mL screw-cap cryovials containing cell suspensions, serum aliquots, and concentrated protein samples
Pharmaceutical stability and retain-sample programs that archive 5 mL vials at −80 °C for defined holding periods
Environmental and water-quality testing labs storing 5 mL sample tubes from field collection runs
Frequently Asked Questions
Will standard 5 mL round-bottom tubes fit?
The 22.6 mm wells accommodate most 5 mL cryotubes and screw-cap vials. Verify your tube's outer diameter is ≤ 22 mm for a proper fit. Some wide-body 5 mL centrifuge tubes may be too large.
Can I use this box in liquid nitrogen?
Corrugated polypropylene is rated to −80 °C. For liquid-nitrogen vapor-phase or immersion storage, use polycarbonate cryoboxes such as the Heathrow Arctic Squares® line.
What is the height of this box?
The assembled box is 2.9 inches (7.5 cm) tall — taller than a standard 2-inch cryobox. Verify that your freezer rack shelf spacing accommodates 3-inch-height boxes.
Quality Assurance
