Everstill Active Benchtop Isolator

Everstill active benchtop vibration isolation platform
  • Overview +

    Introducing Everstill™, TMC's latest breakthrough in advanced floor vibration control. The patented Everstill K-400 is a benchtop active vibration cancellation platform that incorporates a "serial type" active architecture. This, combined with velocity sensors for enhanced low frequency sensitivity, attains a dramatic level of low frequency vibration attenuation.

    Designed to isolate ultra-precision instruments from building floor vibration down to below 1 Hz, the Everstill K-400 is ideal for optical microscopes, SPMs, and metrology instruments. With Gainmatch™ (patent pending), easily choose one of three gain settings to achieve optimal performance in your environment.

    With technology evolving from TMC's STACIS® piezoelectric vibration cancellation, Everstill is an active hard-mount that cancels vibration starting at 0.7 Hz. Specifically designed for maximum low frequency performance, Everstill excels in the critical 1-10 Hz range where precision instruments tend to be the most sensitive.

    The portable, compact design is ideally suited for easy installation on work benches and tables. The only input requirement is power from a standard AC outlet.

  • The Everstill Advantage +

    Superior low frequency performance. Starts to isolate at 0.7 Hz. Dramatic vibration cancellation, especially in the critical 1-10 Hz range

    Patented active vibration cancellation technology. Ideal for small, lightweight, ultra-precision instruments

    Active hard-mount. No air. Robust plug and play design

    Advanced Vibration sensor technology. Incorporates geophone type velocity sensors for sub-Hz performance. Better low frequency sensitivity than accelerometers.

    Gainmatch™ (patent pending) to optimize performance. A switch allows users to easily choose between 3 gain settings. This ensures maximum vibration cancellation with assurance of stability for different user environments.
