Centrifuge Tubes

Centrifuge tubes are available in various volume capacities, configurations, materials, and closure types, and some may be sterile and non-sterile. Capacities can scale from 0.1mL to over 100mL. The most common centrifuge tube sizes are 15mL and 50mL. The sizes 1mL and 2mL are categorized as microcentrifuge tubes. Centrifuge tubes contain liquid during the centrifugation process, during which the sample is separated into components by rotating it around a fixed axis. Most lab centrifuge tubes and sterile microcentrifuge tubes include a conical bottom that collects solid of the sample's heavier parts. All centrifuge tubes must be suitable to withstand centrifugal pressure, which happens during use.

What is the diameter of a 15 mL Falcon?

The diameter of a 15 mL Falcon tube is approximately 17 mm.

What is the diameter of a 50ML Falcon tube?

The diameter of a 50 mL Falcon tube is approximately 29.5 mm.

Are centrifuge tubes reusable?

Centrifuge tubes can be reusable or single-use, depending on the material and design. Reusable centrifuge tubes, typically made of durable materials like glass or high-grade plastic (e.g., polycarbonate or polypropylene), are designed to withstand repeated autoclaving and use. They are commonly used in applications requiring sterilization and long-term durability.

Why is the Falcon tube conical?

The Falcon tube is conical to facilitate the collection and separation of materials during centrifugation. The tapered design allows solids or denser components, such as cells or precipitates, to concentrate at the bottom of the tube in a well-defined pellet, making it easier to separate them from the liquid supernatant.

What are the advantages of glass centrifuge tubes over plastic ones?

Glass centrifuge tubes offer several advantages over plastic ones, particularly in applications requiring durability, chemical resistance, and reusability. One key benefit is their superior chemical resistance, as glass is inert to various solvents, acids, and bases that might degrade or react with plastic

What is polycarbonate tubing used for?

People use polycarbonate tubing in a variety of applications due to its strength, transparency, and resistance to impact and high temperatures. It is commonly used in laboratory and medical settings for fluid transfer, protective housings, and optical experiments where clear visibility of contents is required.
