Thermo Scientific Tube Rack 24 Place 50 ml Green 10 Racks

Description

VWR Tube Rack – 24 Places, 50 mL Capacity, High-Contrast Green Matrix, Heavy-Duty Polypropylene, Stackable Benchtop Organizer (MPN: 5970-0430 / 20901-680)

The VWR 5970-0430 (also distributed under VWR catalog ID 20901-680) is an instrument-grade, high-durability laboratory tube rack engineered for the stable organization, transport, and processing of large-format biological samples. Structured with a 24-place grid layout arranged in a symmetrical 4 x 6 array, this rack is optimized to accommodate standard 50 mL conical centrifuge tubes and similar vessels up to 30 mm in diameter. Injection-molded from premium, chemical-resistant high-density polypropylene (PP), the rack features a multi-tier interlocking architecture with alpha-numeric indexing molded directly onto the top deck. This design ensures absolute sample tracking while its robust, non-skid footprint maintains structural balance on open laboratory benchtops, inside shaking incubators, or during cryogenic deep-freeze storage cycles.

Technical Performance and Design

• Premium Polypropylene Matrix Core: Fabricated from high-purity, rugged polypropylene. This material provides exceptional resistance to impact degradation, cracking, and cracking under repetitive stress, ensuring a long operational lifespan.

• Molded Alpha-Numeric Tracking Deck: Outfitted with permanent, high-contrast matrix coordinates (Rows A–D, Columns 1–6) molded into the top plate. This enables immediate, error-free tracking of individual patient samples and master aliquots during processing.

• Double-Tier Stabilization Wells: Designed with a matching mid-tier indexing level and cross-braced bottom retention tracks. This architecture grips the conical tips of 50 mL tubes tightly, preventing vertical wobbling, rotation, or fluid splashing during transit.

• Universal Temperature and Autoclave Validation: Validated to withstand rigorous thermal decontamination loops inside standard laboratory steam autoclaves up to 121°C (250°F). The polymer core remains dimensional stable down to -80°C, making it exceptional for long-term ultra-low temperature archiving.

Key Benefits and Applications

• 50 mL Conical Centrifuge Organization: The industry-standard benchtop platform for preparing cell pellets, downstream extractions, and bulk reagent stocks in clinical and biotech workflows.

• Color-Coded Batch Separation: The high-contrast green hue provides an immediate visual indicator to isolate specific batches, clinical cohorts, or hazardous materials at a glance, minimizing mixing errors across team cross-shifts.

• Optimized Drainage Matrix: Outfitted with teardrop-shaped slots at the bottom of each retention well to prevent condensation accumulation and fluid pooling, keeping tubes completely readable and clean.

• Ergonomic End-Grip Handling: Engineered with wide, reinforced structural end-plates that serve as built-in handles, allowing secure, slip-free transportation even while wearing thick nitrile cleanroom gloves.
