High-Performance Medical Tube for Rapid Centrifugation – Nalgene™ 3138-0016
The Nalgene™ 3138-0016 tube, manufactured by Thermo Fisher Scientific, is designed for laboratories that require consistent performance and high reliability for high-speed centrifugation applications. This 16 mL model is designed to withstand a maximum centrifugal force of 50,000 ×g, making it ideal for cell separation processes, nucleic acid extractions and protein purifications.
Its polycarbonate design ensures exceptional mechanical strength, allowing it to be used repeatedly in refrigerated or non-refrigerated centrifuges. The transparency of the material makes it easy to view interfaces and sediments without opening the tube, a valuable feature in medical environments where sample integrity must be preserved at every stage.
The 3138-0016 tube has a round bottom and a constant diameter of 17.8 mm, which promotes even force distribution in the rotor, thus limiting imbalances. Its height of 106.7 mm allows compatibility with standard configurations while maximising the usable space for intermediate volumes.
Thermo Fisher recommends the use of suitable sealing closure caps (15 mm diameter) to ensure a perfect seal, especially at high speeds or when handling potentially hazardous substances. The tube is autoclavable, allowing safe reuse after sterilisation at 121°C for 15 minutes, provided that the recommended protocols are followed.
This product is commonly used in medical, hospital and pharmaceutical laboratories, particularly for analyses where pellet accuracy and separation quality are critical to the validity of the final result. Its durability makes it an economical choice, even in the context of repeated sterilisation.
Its non-tapered design also allows for easier sample recovery by pipetting or aspiration, minimising losses during critical analysis steps.
