Manufacturer Description

The Beckman Coulter SW 41 Ti is a high-performance swinging-bucket ultracentrifuge rotor designed for the Optima series. Constructed from high-strength titanium, this rotor is optimized for rate-zonal and isopycnic separations. The swinging-bucket design allows tubes to move from a vertical to a horizontal position during acceleration, ensuring that gradients remain undisturbed and providing superior resolution for delicate biological samples.
