Choosing the Optimal Wire Test Tube Racks with Marlin Steel

Stainless steel test tube racks are the optimum choice for physicians, researchers, scientists, and laboratory assistants to safely and efficiently conduct testing and experiments. More resilient than plastic, foam, or aluminum test tube racks, metal wire racks are easier to clean, holding their integrity against excessive weight, heat, or force.

Since 1968, Marlin Steel has been creating custom metal forms. Our wire products are manufactured in the USA using 304-grade stainless steel for optimum performance and flexibility. An electropolished finish is available for an overall smooth look and feel.

Our custom test tube racks, which can hold up to 72 test tubes, were recently used by the CDC in the fight against COVID-19.

What are Marlin stainless steel test tube racks?

Test tube racks are an essential part of the medical and pharmaceutical industry. They are not only useful for organizing test tubes but have the unique ability to hold multiple test tubes in an upright position.

Stainless steel wire racks are highly effective in laboratory settings because they are sterile and non-corrosive to bodily fluids. Test tube racks provide protective storage and prevent breakage during the autoclave sterilization process, avoiding the risk of contamination.

Transporting and cleaning test tubes is simplified when using a wire rack. 

Product Features

  • Material: Stainless steel is recyclable and offers greater sustainability. It can efficiently withstand sterilization and cleaning processes. The metal is durable, versatile, and compatible with hot plate usage.
  • Design: The wire rack has small legs with 2.5 cm to 5 cm feet, which allows for a gap around the bottom for steady airflow and ventilation.
  • Quantity: The wire racks can house up to 72 test tubes.
  • Test Tube Size: Test tube racks can accommodate test tubes ranging in size from 10 mL to 20 mL without the risk of falling through or need for modification.
  • Coating: There is no epoxy coating on the wire rack.
  • Temperature Resistance: Stainless steel test tube racks have an operating range of -150F to +1600 F (-101C to +871C) and can withstand cyclic or rapid temperature fluctuations, outperforming racks made from other materials.


Custom Racks

Customized options for stainless steel wire racks include an electro-polished finish that has the following benefits:
