VWR Wire Tube Rack 24 Places Poxygrid 40 mm Orange Epoxy Coat Lot of 2 Racks

VWR Poxygrid Wire Tube Rack – 24 Places, 40 mm Wells, Orange Epoxy-Coated Steel Matrix, Autoclavable Contamination Defense (MPN: 20901-572 / 11314-118)

The VWR Poxygrid Wire Tube Rack (distributed under VWR catalog configurations 20901-572 and cross-referenced with Bel-Art family line 11314-118) is an instrument-grade, high-durability laboratory storage containment matrix engineered for heavy-duty tube stabilization and handling workflows. Structured with a 24-place layout arranged in a 4 x 6 grid array, this rack features extra-wide 40 mm (40 millimeters) square wells. Fabricated from high-tensile structural steel wire, the entire frame is heavily encased in a chemical-resistant, bright orange epoxy coating. This protective layer creates an insulated cushion that guards glass tubes against micro-fractures while providing a smooth, non-porous surface that resists aggressive laboratory acids, organic solvents, and routine cleaning solutions.

Technical Performance and Design

• Heavy-Duty Epoxy-Insulated Steel Core: Built from hard-drawn, welded steel wire coated in a thick, impact-resistant orange epoxy enamel. The continuous outer jacket isolates the core metal from corrosive fluids, preventing rust, flaking, and ambient surface oxidation.

• 40 mm Large-Diameter Well Matrix: Configured with a 4 x 6 open grid holding exactly 24 large-format vessels. The 40 mm well clearances accommodate heavy laboratory glassware and large polymer vials without binding, scraping, or sticking during transit.

• Double-Tier Slotted Tube Alignment: Designed with a parallel top grid and a matching mid-tier indexing deck supported by a solid grid floor. This double-tier geometry ensures excellent vertical stability, keeping tall or top-heavy tubes securely upright to prevent accidental tips.

• Universal Autoclave Validation: Validated to withstand rigorous thermal decontamination loops inside standard laboratory steam autoclaves. The epoxy coating handles repetitive heat and high pressure up to 121°C (250°F) without peeling, bubbling, or softening.

Key Benefits and Applications

• Large Format Tube Management: The ideal storage benchmark for holding 50 mL conical centrifuge tubes, large BOD bottles, corporate chemical mixing vials, and wide-mouth specimen jars.

• Water Bath Submersion Processing: The heavy steel frame provides excellent negative buoyancy, keeping the rack firmly anchored at the bottom of deep laboratory water baths without floating or drifting out of position.

• High-Contrast Hazard Color Identification: The bright orange finish serves as an excellent visual cue for clinical workspaces to isolate high-hazard samples, radioactive reagents, biohazard extractions, or specific processing batches at a glance.

• Airflow-Optimized Drainage Design: The minimalist, open wire mesh architecture allows total air circulation and water drainage. This feature prevents fluid pooling and condensation buildup, keeping tubes clean and readable during cold-room refrigeration storage.
