    Key Features

    • The intuitive user interface consists of an interactive color touch-screen and a positive feedback keypad for quick protocol setup and storage
    • For routine spins, simply enter speed, time and temperature parameters
    • Real-time control means the sample is ready when you are—schedule delayed start/stop times
    • Program memory saves time by storing up to 20 programs into memory along with User ID and comments

    Outstanding Control with UltraSecur

    • Embedded software enables better control of multi-user access, greater convenience and improved safety
    • User lockout feature prevents unauthorized access
    • Rotor life management tracks rotor usage and alerts when rotors need to be serviced or replaced

    Excellent Space Savings and Efficiency

    • Runs quietly for use anywhere in the lab
    • Less than 20A load reduces power consumption and eliminates burden on HVACs
    • 3 in. lower deck height for easier rotor loading/unloading; door opens with just a push
    • Smaller footprint utilizes minimal floor space
    • Imbalance-Tolerant Drive saves time with visual tube balance

    Easier Sample Loading for Safer Separations

    • Unique StepSaver™ rotors use cartridges to streamline sample loading and unloading steps, minimizing sample loss
    • Thermo Scientific™ SureSpin™ rotors prevent swinging buckets from being loaded improperly, avoiding sample loss, run shut-downs and rotor failures

    Simulate New Protocols and Ensure Regulatory Compliance

    • Windows™-based Compass run simulation software allows development of separation protocols on laptop or PC
    • Set run parameters and convert run values
    • Calculate k-factors, pelleting times, de-rating speeds, molecular masses, s-value conversions, and crystallization times
    • Simulate particle sedimentation and diffusion for complex rate-zonal separations

    Ordering Information:

    Optional accessories include rotors, software, printers, user lockout device, and HEPA filter kit. WX Series accepts ultra rotors from most major manufacturers. Rotors are sold separately.
