United Scientific Wet/Dry Test Tube Racks – 20mm, 40-Place, 4x10 Holes, Autoclavable Polypropylene (PP), Pack of 6

The United Scientific 20mm Wet/Dry Test Tube Racks are a cost-effective, durable solution for organizing and securing tubes in both wet and dry lab environments. Made from a specialized polypropylene (PP) blend, these racks are designed to sink in water baths and remain stable—even under agitation—making them ideal for water bath incubations, wet sample handling, or tube storage.

Each rack holds 40 tubes (20mm diameter) arranged in a 4x10 format, with an alpha-numeric grid on the top tier for easy sample identification. Designed to maximize lab efficiency, these racks are autoclavable, resistant to chemicals, and stackable when not in use, saving space in crowded labs.

Their robust build makes them a reliable alternative to more expensive tube racks, offering durability without compromising function. Each pack includes 6 identical racks in white, with additional custom color options available upon request.

Ideal for educational, clinical, industrial, and research labs, these wet/dry test tube racks deliver the performance and flexibility you need at a price that fits your budget.
