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

Crystal Technology UF-542 20-Place Upright Freezer Storage Rack (5 Long x 4 High) – Case of 4 Racks

The Crystal Technology & Industries UF-542 is a premium, heavy-gauge stainless steel inventory matrix designed for high-density cryogenic specimen archiving. Configured as a case of 4 individual racks, each unit features a 20-place side-access grid structured 5 boxes deep (lengthwise) by 4 boxes high (vertically). Engineered specifically for standard 2-inch (53mm) storage boxes, this system allows biorepositories and clinical laboratories to maximize the internal depth of ultra-low temperature (ULT) upright freezers down to -86°C.

Technical Performance & Design

• Deep-Cabinet 5 x 4 Matrix Optimization: Tailored for ultra-low freezers with deep, narrow shelf configurations. The 5-box depth fully utilizes horizontal space, while the 4-box vertical profile easily fits standard compartment clearances.
• Heavy-Gauge Stainless Steel Metallurgy: Fabricated from high-tensile, corrosion-resistant stainless steel alloy that resists warping, frost-binding, and degradation from aggressive chemical sanitizers.
• Precision Side-Access Slots: Designed with open side-loading boundaries featuring completely deburred, smooth edges, permitting lab technicians to pull a single targeted box without exposing adjacent samples to room temperature currents.
• Integrated Wire Pull Handles: Equipped with a robust front-mounted wire handle securely welded to the frame, ensuring an operator wearing thick cryogenic gloves can smoothly extract the loaded rack from tightly frosted freezer bays.

Key Benefits & Applications

• Bulk Biobanking & Clinical Storage: Packaged as a 4-rack case to streamline large-scale fit-outs of new or existing -80°C upright freezer units.
• Sample Temperature Protection: The side-retrieval format prevents the vertical chimney effect common to top-loading racks, significantly mitigating thermal stress on remaining shelf inventory.
• Universal 2-Inch Compartment Fit: Accommodates standard industry box footprints, whether utilizing 81-cell or 100-cell grid layouts for microtubes, blood collection tubes, and cryovials.
• Validation & Tracking Compatibility: Features a solid front steel plate that provides an ideal surface for attaching permanent barcode labels, magnetic location tags, or laser-etched inventory markers.

Specifications reflect standard nominal metrics for the bare stainless steel frame assemblies. Storage boxes, cell dividers, and internal grid liners are not included in the UF-542 case package and must be specified independently to match your exact vial geometry.
