This efficiency is reflected in the k-factor, which accounts for other contributing factors such as maximum speed as well as maximum and minimum radius. When combined with high speeds, this increases run efficiency, enabling the scientist to spend less time preparing their samples. When workflow efficiency and the need to accelerate sample preparation time is most important, scientists need to focus on rotors that can run labware that provides shorter path lengths for their sample to travel. In addition to the maximum speed of a rotor (in rpm or g force) to compare efficiency, other factors such as the geometry of the cell hole, and tube length, also contribute to rotor performance. This provides redundant safety checks in the system to ensure safe operation. To ensure that a rotor does not run above its rated speed, Beckman Coulter’s Dynamic Rotor Inertia Check (DRIC) is incorporated into all high performance centrifuges.

This is vital with the speeds of 100,000 rpm and over 1,000,000 x g that modern rotors can generate. These rotors must comply with strict safety standards such as IEC 60 for mechanical and electrical safety protection. The calculator will quickly check if the lab’s existing rotor supply has the capacity or will identify an alternative.īeckman Coulter centrifuges are designed and tested as a complete system so that safety and performance can be maximised. With a large volume capacity ultracentrifuge, a lab can carry out its own deletion of fetal bovine serum (FBS) from exosome material, rather than incur the cost of buying FBS with contaminants removed, from external sources. This process can be made more efficient with rotors offering high RCF (800,000 x g) to maximise the efficiency of separating nano-sized materials such as exosomes. Rotor Capabilities for Diverse Applicationsīeckman Coulter Life Sciences provides a large variety of rotors to meet the needs of the most demanding research, including the expanding area of exosome characterisation and analysis. These include a unique online rotor calculator which scientists anywhere in the world can use to determine individual rotor parameters such as maximum rpm and run-time conversions. They offer precise temperature control and rapid attainment, delivering maximum separation purity in the shortest time possible.Īs global specialists in rotor technology, Beckman Coulter offers a range of resources to maximise a lab’s investment in the right centrifuge. Ultracentrifuges deliver centrifugal forces of greater than 100,000 x g (and up to 1,000,000 x g). Beckman Coulter’s high performance Optima and Avanti centrifuges offer high capacities, high RCFs and exceptional versatility with interchangeable rotors for different applications. Several components in a centrifuge contribute to optimal efficiency, including relative centrifugal field (RCF), rotational speed, cell angle, and rotor volume.
