Thermo Scientific Freezer Rack 20 Places 5x4 for TDE and TSX Series

Thermo Scientific Adjustable Side-Access ULT Freezer Rack – 20-Place Capacity, For 2-Inch Cryo Boxes, Premium Stainless Steel, Optimized for 5-Shelf TSX and TDE Series Freezers (MPN: 1950518)

The Thermo Scientific 1950518 is a high-density, laboratory-grade ultra-low temperature (ULT) inventory management rack precision-engineered to organize and maximize cold storage space within mechanical freezers. Fabricated from premium, corrosion-resistant stainless steel, this side-access storage module features a 20-place capacity optimized specifically for standard 2-inch (50 mm to 53 mm) cryogenic storage boxes. The internal shelving brackets within the rack are fully adjustable, allowing lab managers to dynamically modify slot spaces to fit non-standard sample containers if workflows shift. Explicitly tailored to match the interior dimensions of Thermo Scientific's advanced 5-shelf TSX and TDE Series upright freezers, this industrial-grade rack provides smooth box insertion and retrieval paths, streamlining sample logging across busy biorepositories, clinical trial banks, and research laboratories.

Technical Performance and Structural Design

• Premium Stainless Steel Matrix: Fabricated from high-tensile, industrial-grade stainless steel engineered to withstand continuous sub-zero mechanical stress down to minus 80 C without becoming brittle. The surfaces naturally resist frost-induced oxidation and chemical cleaning passes.

• Granular Adjustable Internal Shelving: Outfitted with unique adjustable internal support tracks. Unlike fixed-welded frames, these internal dividers can be vertically reconfigured to alter single shelf spacing clearances, adapting to custom fluid reservoirs or variable vial box heights.

• Efficient Side-Access Extraction: Designed as an ergonomic side-loading chassis. This geometric configuration enables technicians to rapidly review index labels and slide individual sample boxes out from the flank without disturbing adjacent boxes in the row.

• Deburred Safe-Edge Boundary Manufacturing: Precision-cut and micro-deburred across all raw sheet-metal intersections. This ultra-smooth corner processing prevents physical glove tears, skin punctures, and metal-on-metal cabinet shelf scratching during quick sample transfers.
