Beckman Coulter XE-90K Ultracentrifuge, 485 kg, Beckman Coulter (CAT#: STEM-LCPO-0100-LGZ)

Under the hood is the same Optima reliability throughout the Superline. Beckman ultracentrifuges can also be used for gradient separations and protein purification, and feature a dynamic temperature regulation system that efficiently maintains optimal processing temperatures. The Optima™ XE-90K features a shallow rotor groove design that provides a convenient operating height for most users. The vacuum-encapsulated induction drive is essentially frictionless and will provide years of trouble-free operation with virtually no wear!

The biggest change to the XE series, specifically the Optima™ XE-90k system, is that it features a touchscreen interface that allows users to manage and control temperature, RPM, acceleration/deceleration and time settings. RPM settings allow up to 70000.

The XE series operates using the Dynamic Rotor Inertia Check (DRIC) function. This feature identifies rotor imbalances, preventing system failure and equipment damage before the unit performs actual separation. Additional features of the Beckman Optima™ XE-90K centrifuge include built-in rotor and tube catalogs, intelligent recording software, dual display of 'setup' and 'actual' running parameters, and simple user settings including automatic preheating, precooling, Vacuum and dry cycle.
