Taller 3-inch (75 mm) cryoboxes need racks with wider slot heights that 2-inch racks simply don't provide. The Heathrow Scientific Upright Freezer Racks for 3-inch cryoboxes are purpose-built with expanded vertical clearance for these larger boxes, available in 4 × 4 (16-place) and 5 × 4 (20-place) stainless-steel configurations. Each slot accepts any standard-footprint 3-inch cryobox, and the corrosion-resistant steel frame slides on side rails for easy access in upright −80 °C and −150 °C freezers.
Features and Benefits
Two Configurations: 4 × 4 (16-place) and 5 × 4 (20-place) for different freezer sizes and storage needs.
3-Inch Box Clearance: Expanded vertical slot height accommodates 75 mm cryoboxes that don't fit 2-inch racks.
Stainless Steel: Corrosion-resistant construction for long service life in humid freezer environments.
Side-Rail Sliding: Smooth in-and-out access for box retrieval.
Universal Compatibility: Accepts any brand of standard-footprint 3-inch cryobox.

Laboratory Applications
Organizing upright freezers with 3-inch cryoboxes holding taller cryovials, 3–5 mL tubes, or extra-height sample containers
Biobanking facilities transitioning to 3-inch boxes for larger-volume vials while maintaining rack-based organization
Facilities managing mixed 2-inch and 3-inch inventories — dedicate one rack type per box height for consistent organization
Frequently Asked Questions
Can I use 2-inch boxes in a 3-inch rack?
Physically yes — 2-inch boxes will fit but will have extra vertical clearance. For best space efficiency, match box height to rack slot height.
What is the price difference between 4 × 4 and 5 × 4?
Both configurations are the same price ($26.00). The 5 × 4 is taller (16 in vs. 12.8 in) and holds 4 additional boxes. Choose based on your available freezer height.
