Centrifugation is an invaluable tool in research laboratories for separating and purifying complex mixtures. Several rotor types are available that vary in their angle relative to the axis of rotation, and distinct use cases for each type have been realized. The buckets in swinging-bucket rotors swing out to 90° as centrifugal force is applied, resulting in pellets being formed directly at the bottom of the tube or bottle. This swing-out mechanism enables unique purification techniques like rate-zonal separations and affords the use of adapters to boost versatility. In this webinar we will focus on selecting and implementing rotors and consumables, with a focus on situations in which swinging-bucket rotors are optimal.
In this webinar you will learn:
- Advantages and disadvantages of swinging-bucket rotors for primary recovery and purification
- Principles and case studies on rate-zonal separations
- How to choose the right swinging-bucket rotors and consumables
