The 70.1 Ti Fixed-Angle Rotor: Precision, Safety, and Performance for High-Speed Ultracentrifugation
The 70.1 Ti rotor from Beckman Coulter is a high-quality component specifically engineered to meet the rigorous demands of preparative ultracentrifugation. Manufactured from titanium—a material known for its durability, corrosion resistance, and light weight—this rotor delivers exceptional performance and longevity under intensive laboratory conditions. Designed for use in Beckman Coulter Class H, R, and S ultracentrifuges, it is ideally suited to high-precision applications such as subcellular fractionation, virus isolation, and DNA purification in biomedical and molecular biology laboratories.
Capable of reaching an impressive maximum speed of 70,000 revolutions per minute, the rotor generates a relative centrifugal field (RCF) of up to 450,000 × g. With a fixed angle of 24 degrees and 12 tube cavities, it can process up to twelve 13.5 mL tubes per run, giving it a total capacity of 162 mL. Its compact yet efficient design is perfect for workflows requiring rapid separation of fine particles or gradients, including sucrose and cesium chloride protocols. With a k-factor of 36, it offers highly efficient pelleting while minimizing run times.
Every detail of the 70.1 Ti rotor has been designed to optimize laboratory safety and ease of use. A built-in overspeed disk is monitored by the ultracentrifuge’s optical detection system, which automatically stops the run if the rotor exceeds its rated speed. The Buna N rubber O-rings in the lid and handle provide excellent sealing, ensuring that internal pressure is maintained consistently throughout the centrifugation process. In the event of tube leakage, four safety vents in the lid prevent pressure buildup, preserving both equipment integrity and operator safety.
Ease of handling is a key benefit of this rotor. It can be loaded and balanced in less than ten minutes, thanks to the symmetrical tube arrangement. Its acceleration and deceleration times are optimized—around 6 and 4 minutes respectively—boosting throughput without compromising reliability. The rotor is also easy to maintain and clean. It is compatible with Beckman’s Solution 555™ for safe cleaning, and it can be autoclaved at 121 °C, making it suitable for workflows that require sterilization.
The Beckman Coulter 70.1 Ti rotor offers a blend of reliability, performance, and user-friendly design that makes it an essential part of any laboratory involved in high-speed separations. With its titanium construction, integrated safety features, and compatibility with a broad selection of tubes and accessories, this rotor is a trusted solution for demanding applications in life sciences, biotechnology, and clinical research.
