Utilizing Minus K's patented breakthrough technology, the Compact Tabletop (CT-2) offers the best performance available in a 2.7-inch-tall isolation platform. Better horizontal performance and more payload ranges for heavier instruments are features of this system.
This fully passive mechanical isolator performs 10–100 times better than a full-size air table. It accomplishes this without the use of air or electricity.
This incredibly user-friendly vibration isolation platform offers the company’s signature 0.5 Hz vertical natural frequency and approximately 1.5 Hz horizontal natural frequency. It requires just two adjustments. The CT -2 is perfect for all kinds of benchtop microscopes.
This is the thinnest, most portable, and easiest-to-use isolator that has ever been made available with this kind of performance.

Performance |
- Horizontal frequencies are weight-dependent.
- Horizontal frequency of ~1.5 Hz is achieved at or near the upper limits of the payload range.
- At the lower payload weights the horizontal frequency will increase.
- Vertical frequency is tunable to 0.5 Hz throughout the payload range.
