Crystal Technology Freezer Rack Upright ULT 20 Places 4 x 5

Crystal Technology UF-452 Upright ULT Freezer Rack, 20-Place (4 x 5 Configuration) – Single Unit

The Crystal Technology UF-452 Freezer Rack is a heavy-duty, stainless steel inventory management rack engineered for high-density sample storage in standard upright ultra-low temperature (ULT) freezers (operating down to minus 80 degrees Celsius). Designed to hold up to 20 standard 2-inch (or 50 mm) cryogenic storage boxes, this rack features a 4-box high by 5-box deep (4 x 5) matrix layout. Fabricated from corrosion-resistant, laboratory-grade stainless steel, the UF-452 delivers structural rigidity and long-term durability under continuous deep-freeze thermal stress. It maximizes internal chamber volume while allowing fast, organized access to individual storage boxes without disturbing adjacent inventory.

Technical Performance & Structural Design

• Corrosion-Resistant Stainless Steel Frame: Constructed from heavy-gauge 304-grade stainless steel with fully welded seams. This resists rust, mechanical distortion, and structural fatigue during repeated thermal cycling between room temperature and sub-zero environments.
• Precision 4 x 5 Compartment Grid: Configured with 4 vertical shelf levels and 5 horizontal compartments per level to securely house up to 20 standard square cryogenic boxes (2-inch height, 5.25 x 5.25 inch footprint).
• Integrated Handle & Pull-Bar Assembly: Outfitted with an ergonomic front handle for smooth, balanced extraction from crowded upright freezer compartments, even when wearing thick cryogenic safety gloves.
• Optimized Airflow & Liquid Nitrogen Drainage: Features open-rail side panels and bottom cutouts to promote uniform cold air circulation throughout the rack and facilitate rapid liquid drainage during room-temperature defrost cycles.

Key Benefits & Applications

• Maximized Internal Chamber Density: Converts open freezer cavity space into a structured, indexed inventory system to optimize sample capacity per cubic foot.
• Biobank and Repository Organization: Ideal for clinical repositories, genomic biobanks, and pharmaceutical research facilities managing large-scale vial collections in 81-place or 100-place cryo-boxes.
• Thermal Shielding During Sample Access: Allows lab personnel to pull a single targeted rack to retrieve a sample, preserving the thermal stability of neighboring samples remaining in the freezer.
• Maintenance-Free Long-Term Utility: Smooth, burr-free welds prevent glove snagging and ensure long-term ease of cleaning and chemical sanitation.
