NuAire Incubator Shelf Perforated Stainless Steel 19.25 in. Square Shelf

The NuAire NU-1557 is a genuine OEM replacement accessory designed to restore or expand the storage capacity of NuAire Autoflow laboratory incubators. Engineered specifically for the standard 6.64 cubic foot chamber geometry, this shelf ensures a precise fit that prevents rattling or instability during daily use. Manufactured from high-grade electropolished stainless steel, it is built to withstand the humid, high-CO2 environments of modern cell culture laboratories.

Technical Performance and Design

• Optimized Airflow Geometry: Features a precision-perforated hole pattern that allows for unobstructed vertical laminar airflow, ensuring uniform temperature and CO2 distribution across all levels.

• Corrosion-Resistant Material: Constructed from heavy-gauge Type 304 electropolished stainless steel to prevent rusting, pitting, or degradation in high-humidity environments.

• Aseptic Integrity: The solid metal construction is fully autoclavable, supporting rigorous sterilization protocols to prevent cross-contamination between sensitive cell culture batches.

• Stable Load Bearing: Designed to maintain structural rigidity under the weight of multiple heavy glass roller bottles or full stacks of multi-well plates.
