Manufacturer Description

The Beckman Coulter SW 28 is a high-capacity swinging-bucket rotor system designed for large-volume density gradient separations. These titanium buckets are engineered to withstand the extreme forces of ultracentrifugation while maintaining the horizontal orientation required for high-resolution fractionation. This matched set is designed to ensure balanced operation and drive-spindle longevity in Beckman Optima series floor-model ultracentrifuges.
