Centrifuge tubes are designed with specific features to withstand the forces experienced during centrifugation, ensuring the safety of both the sample and the laboratory equipment. Here are key design considerations that contribute to the ability of centrifuge tubes to endure centrifugal forces:

 

Material Selection:

 

The choice of materials is crucial. Plastic centrifuge tubes are typically made of durable plastics, such as polypropylene or polyethylene, known for their high strength and resistance to chemical reactions.

Specialized materials may be used for specific applications, such as ultra-clear tubes for visibility or materials that are compatible with certain solvents or reagents.

Wall Thickness:

 

The thickness of the tube walls is carefully designed to provide structural integrity during centrifugation. Thicker walls can better withstand higher forces, but the design aims to balance strength with weight considerations.
