USA Scientific Upright Freezer Rack for Microplates 5 Place Rack

USA Scientific Stainless Steel Upright Freezer Rack for Microplates – 5-Place Column Layout, SBS/ANSI Microplate Footprint, Open-Front Design (MPN: US-4515)

The USA Scientific US-4515 is a heavy-duty, corrosion-resistant stainless steel freezer rack specifically engineered for high-density vertical storage of ANSI/SLAS microplate-footprint labware inside upright ultra-low temperature (-80 C) and standard (-20 C) laboratory freezers. Designed with an open-front 5-compartment long layout, each section accommodates standard microplate base footprints (up to 5 in. L x 3-3/8 in. W per slot). Constructed from high-strength passivated stainless steel, this rack features solid side walls, accessible back panels to push plates forward for easy removal, and integrated front handles for effortless maneuvering while wearing thick cryogenic gloves.

Technical Performance and Structural Design

• Corrosion-Resistant Stainless Steel Construction: Precision-welded from industrial passivated stainless steel to withstand severe cryogenic cycling down to -80 C and -150 C without rusting, warping, or structural weakness.

• ANSI/SLAS Microplate Footprint Optimization: Compartments are sized specifically to hold microplate-style footprints (5 in. L x 3-3/8 in. W), allowing plates and 2D barcoded tube racks to stack cleanly without excess lateral shifting.

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

• Ergonomic Glove-Friendly Pull Handle: Built with a sturdy front-mounted handle, allowing operators wearing cold safety gloves to pull the rack smoothly out of frost-covered freezer bays.

Compatible Labware & Box Types

• Standard 96-Well & 384-Well Assay Microplates: Holds approximately 12 to 14 standard-height microplates per column slot (total capacity: ~60 to 70 plates with lids).

• Deep-Well Plates & Storage Blocks: Accommodates deep-well plates (1.5 in. to 2.2 in. height), holding approximately 4 deep-well plates per slot (total capacity: ~20 deep-well plates).

• 2D Barcoded Microtube Racks: Fits SBS-format microtube storage racks (such as Thermo Matrix, Micronic, Azenta/FluidX, and Eppendorf 96-tube rack systems).

• Microplate-Footprint Storage Boxes: Fits specialized plastic and cardboard storage boxes engineered specifically with a 5 in. x 3-3/8 in. base footprint.

• Incompatible Labware Notice: Does NOT fit standard 2-inch square cryo boxes (5.25 in. x 5.25 in.). Standard square cryo boxes require a 4-place-long rack footprint rather than a 5-place microplate layout.

Freezer Compatibility and Sizing Guide

The 21.75" L x 5.5" W x 9.25" H physical bounds of the USA Scientific US-4515 are engineered for Upright Ultra-Low Temperature (-80 C) and Laboratory Freezers. Verify your freezer interior measurements prior to installation:

• Upright ULT Freezers (-80 C / -20 C): 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 inches and a clear vertical inner shelf height of at least 9.5 inches.

• Pre-Purchase Measurement Check: 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.
