Crystal Technology 20-Place Freezer Rack for Standard 2 in. Boxes 4 Long x 5 High Configuration

Crystal Technology UF-452 20-Place Upright Freezer Storage Rack (4 Long x 5 High)

The Crystal Technology & Industries UF-452 is a heavy-duty, pharmaceutical-grade stainless steel inventory rack designed to optimize sample organization within ultra-low temperature (ULT) upright freezers. Featuring a 20-place side-access matrix configured 4 boxes deep by 5 boxes high, this storage rack accommodates standard 2-inch (53mm) cardboard, fiberboard, or polycarbonate cryo boxes. Engineered to withstand temperature extremes down to -86°C, it helps clinical and research laboratories maximize storage density while maintaining efficient sample retrieval paths.

Technical Performance & Design

• Pharmaceutical-Grade Metallurgy: Fabricated from high-tensile, corrosion-resistant stainless steel designed to resist frost deformation and aggressive sanitizers in ultra-cold storage environments.
• Robotic Precision Construction: Built with continuous double welds and fully smoothed, deburred edges to ensure snag-free box insertion while preventing user lacerations during rapid handling.
• Optimized 4 x 5 Matrix Layout: Features a 4-deep (lengthwise) by 5-high (vertical) compartment grid that holds exactly 20 standard inventory boxes, utilizing cabinet depth to minimize unused air space.
• Ergonomic Retrieval Handles: Equipped with heavy-gauge wire handles securely welded to the front face, permitting a single gloved technician to smoothly slide the entire rack assembly out of cold storage bays.
