These 4-way polypropylene cube tube racks feature multiple tube size options. Their small footprint is ideal for benchtop use or under the hood workplace. The tube racks come in three different styles: interlocking, modular, and revolver workstation.

Interlocking racks are suitable for use in ultra-low temperature freezers which go down to -90 °C (-130 °F). You can press the interlocking racks together to form a larger, custom rack.
