When selecting the right rotor for your fixed angle centrifuge, it’s important to understand the key advantages and applications of this essential laboratory tool. Ohaus, a trusted name in laboratory equipment, offers reliable fixed angle centrifuges that are ideal for a variety of applications, including the separation of biological materials, DNA, RNA, and more.
Advantages of Fixed Angle Rotors in Centrifugation
Fixed angle rotors provide faster sedimentation times compared to other rotor types. Because the samples are held at a consistent angle, typically between 30° and 45°, they experience higher centrifugal force, resulting in more efficient and faster separation. This makes fixed angle centrifuges particularly valuable for applications requiring compact pellets, such as the isolation of proteins or nucleic acids. The rotor’s design ensures that heavier components are quickly pulled to the bottom of the tube, which accelerates the entire process.
Comparing Fixed Angle and Swing-Out Rotors
While both fixed angle rotors and swing-out rotors are commonly used in laboratory centrifuges, they have distinct differences. In a fixed angle centrifuge, sediments settle at an angle on the bottom of the tube, which is ideal for high-speed applications where compact pellets are required. On the other hand, swing-out rotors allow the sample to swing outward at various angles, providing even sedimentation at the tube’s base. When choosing between the two, fixed angle rotors are best for high-speed, smaller volume samples, while swing-out rotors offer higher capacity and are preferred for gradient centrifugation.
Ohaus Fixed Angle Centrifuge Features
Ohaus offers a range of fixed angle centrifuge models with advanced features designed to optimize performance. Their fixed angle rotors are engineered for durability and precision, ensuring reliable results in even the most demanding laboratory environments. To maintain optimal performance, it’s essential to regularly clean the rotor and check calibration.
Conclusion
With proper care, your Ohaus fixed angle centrifuge will deliver accurate, high-speed separations for years to come. Whether you’re conducting biological research or preparing samples for sensitive analysis, Ohaus centrifuges are a dependable choice for consistent, efficient results.
