USA Scientific Upright Freezer Rack for Up to 3 3/8 In Boxes 12 Place Rack

USA Scientific Stainless Steel Upright Freezer Rack for Multiple Well Plates – 12-Section Capacity (6 Long x 2 High), Solid Frame with Locking Rods (MPN: 2662-0957)

The USA Scientific 2662-0957 is an industrial-grade, heavy-duty stainless steel freezer rack engineered to optimize vertical sample storage density inside ultra-low temperature (ULT) and standard laboratory upright freezers. Designed with a 12-section layout arranged in a 6-compartment long by 2-compartment high array, this rack accommodates microplates, deep-well plates, assay blocks, and compact tube racks with a standard footprint (up to 5 in. x 3-3/8 in. per section). Built from high-durability, corrosion-resistant passivated stainless steel, it features solid side panels with integrated front handles for effortless maneuvering while wearing cryogenic gloves. Accessible open back panels allow plates to be pushed forward for rapid sample retrieval, while front-facing locking rods secure microplates during transfer and prevent accidental spills or displacement.

Technical Performance and Structural Design

• Corrosion-Resistant Stainless Steel Frame: Constructed from heavy-gauge passivated stainless steel engineered to withstand harsh cryogenic temperatures down to -80 C and -150 C without rusting, warping, or structural fatigue.

• Integrated Safety Locking Rod System: Outfitted with front vertical locking rods that slide securely across the compartment openings, keeping plates and tube racks locked in place during transport.

• Accessible Push-Through Rear Panels: Designed with open rear clearance channels allowing operators to push plates forward from behind for fast, smooth removal without binding or shelf jamming.

• Ergonomic Front Access Handles: Features durable, front-mounted wire handles designed for easy grip when pulling cold racks out of frost-covered freezer compartments using thick low-temperature safety gloves.

Freezer Compatibility and Sizing Guide

The 21.75" L x 5.5" W x 9.5" H physical bounds of the USA Scientific 2662-0957 are standard for Upright Ultra-Low Temperature (-80 C) and Laboratory Freezers. To verify compatibility with your freezer model, check your interior shelf compartment against these guidelines:

• Upright ULT Freezers (-80 C / -20 C): Universally compatible with standard 19 to 28 cu. ft. upright laboratory freezers (including Thermo Scientific Revco/Forma, Eppendorf/New Brunswick, PHCbi/Panasonic, So-Low, and Stirling Ultracold) that feature an interior depth from front to back of at least 22.5 inches and a clear vertical inner shelf height of at least 9.75 inches.

• Pre-Purchase Measurement Checklist: Ensure your inner freezer shelf depth (from back wall to inner door stop) exceeds 22 inches and clear compartment height (distance between inner shelf grids) exceeds 9.5 inches to allow clean door clearance when closed.
