Modular Disk Adapters For Sx4750 Sx4750a And Js-4.3 Rotors Beckman Coulter. 3 Rotors 359154 by Beckman Coulter allows you to customize your SX4750 series GH3.8 and JS-4.3 (BK362734) centrifuge rotors for a wide variety of tube types. These centrifuge disk adapters prevent tangential forces acting on the rotors which can damage delicate separation gels and downstream applications. With the addition of a 26-hole adapter plate you can convert most 12mm rotors and adapters to a variety of different uses. Another advantage to these Beckman Coulter lab centrifuge accessories is that they eliminate stress fractures in high volume rotors which can reduce the number of broken glass parts. These rotor adapter disks resist breakage caused by abrasion and bending which allows you to use the adapters hundreds of times. The quality is unparalleled offering ideal separation of protein from other cellular components. Plus all the adapters are constructed with an extended-height shock cord that absorbs shock more efficiently than round tubing. You can even use the 12mm adapters in the JS-4.3 rotors. The stress corrosion and chemical resistance of all materials involved in the construction of the disk adapter system ensures that all materials will have a long serviceable life. Beckman Coulter rotor adapters have been tested by a number of experts in the lab and have received positive results. They have been tested by a number of specialists and are backed by a solid guarantee. Modular Disk Adapters For Sx4750 Sx4750a And Js-4.3 Rotors Beckman Coulter 359154
