Minus K® Releases New Vibration Isolation Workstation
Minus K negative stiffness vibration isolators employ a revolutionary concept in low-frequency vibration isolation. Vertical-motion isolation is provided by a stiff spring that supports a weight load, combined with a negative-stiffness mechanism (NSM). The net vertical stiffness is made very low without affecting the static load-supporting capability of the spring. Beam-columns connected in series with the vertical-motion isolator provide horizontal-motion isolation. The horizontal stiffness of the beam-columns is reduced by the "beam-column" effect. (A beam-column behaves as a spring combined with an NSM.) The result is a compact passive isolator capable of very low vertical and horizontal natural frequencies and very high internal structural frequencies. Minus K isolators (adjusted to 1/2 Hz) achieve 93% isolation efficiency at 2 Hz; 99% at 5 Hz; and 99.7% at 10 Hz.
Unique features of the MK26 Series Vibration Control Workstation include:
- Ultra-Low Natural Frequencies
- Vibradamped Frame
- Customizable Accessories
- No Air Supply or Electric Power Needed - Easy to Use
- Choice of Tabletops
- Ergonomic Styling
- Class 100 Clean Room Compatible
- Class 10 Available

The MK26 provides for easy adjustment: The Vertical Load Adjustment Crank is a simple manual adjustment which compensates for changes in vertical load; the Vertical Load Adjustment Indicator lets you easily determine the optimum setting using this simple visual indicator; and the Vertical Stiffness Adjustment screw lets you easily dial in a guaranteed ½ Hz or less vertical natural frequency.
The unit has a maximum load capacity of 700 lbs., a maximum tabletop width of 48", and maximum tabletop depth of 36".
