Swinging Bucket Rotors: What Are They And How Do They Work?

Di: Henry

Most fixed-angle rotors have bores at a fixed angle of 45° and the most compact pellet is formed at that angle. Smaller rotor angles result in more diffuse pellet areas. The advantage of fixed-angle rotors is that they don’t have moving parts like swing-bucket rotors. Fixed-angle rotors are therefore exposed to much lower metal stress than swing-bucket rotors. Centrifugation is a laboratory technique that involves the separation of particles from a liquid based on their density and size differences using centrifugal force. Centrifuge with swinging bucket rotors To load a centrifuge with a swinging bucket rotor, all rotor positions must be equipped with buckets, even if they are empty. Using the instrument without buckets may cause rotor damage. Furthermore, you have to make sure that the buckets can be quickly removed.

In addition, the metal pivots of swinging-bucket rotors should be greased regularly, as should the sealing O-ring of biocontainment rotors. Regular cleaning with water higher capacities or just a mild detergent, and immediately cleaning up spills, are important to prevent corrosion by salts from buffers or solutions (especially for metal rotors).

When to Use a Fixed-angle Rotor or a Swing-bucket Rotor?

TX-1000 4 x 1000 mL Swinging Bucket Rotor. Process 4L in a traditional 3L general purpose centrifuge footprint with the TX-1000 rotor. Available in Swinging Bucket Rotor Do not run toxic, pathogenic, or radioactive materials in this rotor without taking appropriate safety precautions. Biosafe containment should be used when Risk Group II materials (as identified in the World Health Organization Laboratory Biosafety Manual) are handled; materials bucket rotors and of a higher group require more than one level of protection. The rotor yoke is made of stainless steel. Black-anodized aluminum buckets and carriers can be run by placing them over pivot pins on the arms of the yoke; they swing out to horizontal position during centrifugation. Transparent covers made of a high-impact plastic are available for the rotor buckets and carriers. Covers have been tested2 to demonstrate containment of microbiological

Blue-anodized aluminum buckets can be run by placing them over pivot pins on the arms of the yoke; they swing out to horizontal position during centrifugation. A tie-down knob secures the rotor to the centrifuge drive hub. Fixed-Angle Rotors- Usually ranging from 14 to 40 degrees relative to the vertical axis, fixed-angle rotors retain tubes at a constant angle. They fit fast pelleting uses. Swinging Bucket Rotors – Under centrifugation, the Swinging bucket rotor: Swinging bucket rotors have buckets that are loaded in a vertical position and during acceleration phase, the rotor buckets swing out horizontally, such that the solution in the tube is aligned perpendicular to the axis of rotation and parallel to the applied centrifugal field.

How to balance swinging bucket centrifuge To load centrifuges with swinging rotors, make sure that all rotor positions are equipped with buckets, even if you leave them empty. Running the instrument without a bucket may damage the rotor. Also, you need to check that the bucket can swing smoothly.

In swinging bucket rotors (designated SW ), containers are held in rotor buckets or attached to the rotor body by hinge pins or a crossbar. The buckets swing out to a horizontal position as the rotor acceler-ates, then seat against the rotor body for support. Learn how to choose and use fixed-angle and swinging-bucket rotors for different centrifugation applications, and how to optimize speed and time. SEALED ROTORS: They prevent the occurrence of leakages or spillages of biohazard chemicals or substances during the work-process. ROTOR RECOGNITION TECHNOLOGY: It detects which rotor type is installed.

Types of rotors Rotors come in three different types. These are swinging bucket rotors, vertical tube rotors, and fixed angle rotors.

Four-place, aluminum swinging bucket rotors are for use in Avanti™ J-26 XP and XPIBK393124 series and J6-MIBK360291 centrifuges. Although rotor components and accessories made by other manufacturers may fit in the SW 32 Ti and SW 32.1 Ti rotors, their safety in these rotors cannot be ascertained by Beckman Coulter. Use of other manufacturers’ components or accessories in these rotors may void the rotor warranty and should be prohibited by your laboratory safety officer. NOTE On some swinging bucket rotors a solid film lubricant coating (dull gray) is added to the bucket flange where the bucket contacts the rotor body. The coating minimizes friction and enables the bucket to swing into the rotor bucket pocket more smoothly.

This type of rotor is mainly used for rate zonal centrifugation, i.e., to separate particles as a function of their size and density, in which the maximum resolution in particle separation is needed (Ohlendieck, 2017). Swinging-bucket rotors are also suitable for isopycnic centrifugation, i.e., separation based on density only.

Learn what centrifuges is, how it works, its essential components, various types, applications in labs and industries, and practical examples. Swinging bucket rotors (horizontal rotors) have the advantage 1000 4 x 1000 mL that there is usually a clean meniscus of minimum area. In a fixed-angle rotor, the materials are forced against the side of the centrifuge tube, and then slide down the wall of the tube.

Differences in Rotors: Fixed-Angle, Swing-Bucket and Vertical The job of the rotor is the generate rotation speeds that helps the separation of the components in a sample. Swinging-Bucket Rotors: Known also as horizontal rotors, swinging-bucket rotors feature buckets that start in a vertical position 路径长度全长 慢速运行时间以及优异的分辨率 and swing out to a horizontal position during centrifugation. The O-rings or gaskets in rotor assemblies or lids, and in swinging bucket caps, are usually made of Buna N elastomer and maintain atmospheric pressure in the rotor if they are kept clean and lightly coated with silicone vacuum grease.

Service life of swing-bucket rotors in case of deviations from the standard laboratory day: Unless specified otherwise, the service life stated applies to both the rotor cross and the buckets. Rotors for a centrifuge are either fixed angles , swinging buckets , continuous flow, or zonal, depending upon whether the sample is held at a given angle to the rotation plane, is allowed to swing out on a pivot and into the plane of rotation, designed with inlet and outlet ports for separation of large volumes, or a combination of these. Figure F.1 demonstrates the
