Crystal Technology 20-Place Freezer Rack 5 x 4 Configuration Case of 4 Racks

Crystal Technology Upright Freezer Rack for 2-Inch Cryo Boxes – 20-Place Capacity, 5 Deep x 4 High Matrix, Corrosion-Resistant Heavy-Gauge Stainless Steel, Side-Access Storage (MPN: UF-542 / UF542)

The Crystal Technology & Industries UF-542 is an industrial-grade, heavy-duty laboratory freezer rack engineered to maximize internal storage optimization and streamline inventory tracking inside ultra-low temperature (ULT) upright freezers. Fabricated from premium, corrosion-resistant heavy-gauge stainless steel, this robust side-access rack features a systematic storage capacity configuration of 5 boxes deep by 4 boxes high, housing up to 20 standard 2-inch (50 mm to 53 mm) cryogenic storage boxes. Built with high-strength precision welds and finished with ultra-smooth edges to protect technicians from nitrile glove tears, this space-maximizing unit acts as a long-lasting sample management blueprint across biorepositories, clinical trial centers, and core cell banking lines.

Technical Performance and Structural Design

• Heavy-Gauge Stainless Steel Architecture: Crafted from premium-grade structural stainless steel designed to maintain absolute rigidity under continuous cryogenic temperature stress. The metal surfaces resist rust, oxidation, and biological degradation from ambient cold-room humidity.

• Ergonomic Side-Access Orientation: Engineered with a convenient side-loading design that allows technicians to rapidly view, pull, or slide individual boxes in and out from the open flank without disrupting adjacent sample rows.

• Safe-Edge Laser Processing: The entire structural frame undergoes advanced laser cutting and deburring protocols. This eliminates sharp burs, ensuring smooth handling transitions when sliding the rack across frozen cabinet shelves.

• Deep-Shelf Storage Optimization: Designed with an extended 27-inch deep profile that utilizes the maximum internal depth boundaries of high-capacity freezers, converting wasted dead space into systematic archival grids.

Equipment Compatibility Baseline

Due to its specialized 27.28-inch depth and 8.86-inch height boundaries, this rack requires a minimum interior shelf opening clearance of 27.5 inches in depth and 9.0 inches in height. It provides direct drop-in alignment with high-capacity upright ULT freezers (19 to 28 cu. ft. / 500L to 800L) from premier lab hardware lines:

• Thermo Fisher Scientific: Fits high-capacity 4-shelf or 5-inner-door upright models within the TSX Series (e.g., TSX60086, TSX70086) as well as legacy Revco RDE / REL and Forma UFX lines.

• PHCbi / Panasonic: Custom-fit for deep-chamber models like the VIP HD / TwinGuard Series (e.g., MDF-DU702VH-PA, MDF-DU901VHA-PA), taking five 27-inch racks side-by-side per shelf layout.

• NuAire Scientific: Fully compatible with large Blizzard Upright ULT Freezers (e.g., NU-99572J, NU-99728J) featuring internal clearance spans exceeding 27.5 inches.

• Eppendorf: Drops into heavy-capacity uprights like the CryoCube F570 and F740 models when internal spacing heights are adjusted to handle the 225 mm vertical clearance profile.
