Stacking loose cryoboxes in a freezer is a recipe for avalanches every time you open the door. The Heathrow Scientific Arctic Squares® 4 × 4 Freezer Rack organizes up to sixteen 2-inch cryoboxes in a rigid stainless-steel frame that slides in and out of standard upright freezers on stable side rails. Each of the 16 slots accepts any standard-footprint 2-inch (50 mm) cryobox — including Arctic Squares® polycarbonate boxes and comparable brands — so you can consolidate hundreds of cryovials into a single, easily retrievable rack unit. The stainless-steel construction resists corrosion in humid freezer environments and wipes clean with common lab disinfectants.
Features and Benefits
16-Place Capacity (4 × 4 Grid): Holds sixteen standard 2-inch (50 mm) cryoboxes — up to 1,600 microtubes when paired with 100-place boxes — in a single organized rack unit.
Stainless Steel Construction: Resists corrosion and rust in the high-humidity environment inside freezers, ensuring long service life without coating degradation.
Universal 2-Inch Box Compatibility: Accepts Arctic Squares® and any other standard-footprint 2-inch cryoboxes, so you can mix brands and materials within the same rack.
Side-Rail Design: Slides smoothly into upright freezers on side-mounted rails, allowing full extension for easy box access without removing the entire rack.
Easy to Clean: Smooth stainless-steel surfaces wipe down with 70% ethanol, bleach solutions, or other standard lab disinfectants.
