CT-2 Ultra-Thin Low-Height Tabletop Vibration Isolation Platform

The Compact Tabletop (CT-2) uses Minus K's patented breakthrough technology allowing for the best performance on the market in just a 2.7 inch tall isolation platform. This unit is an upgrade from Minus K's CT-1 and offers better horizontal performance with additional payload ranges for heavier instruments.

This completely passive mechanical isolator offers 10-100 times better performance than a full size air table. It does this without any air or electricity!

This vibration isolation platform is extremely easy to use and offers our signature 0.5 Hz vertical natural frequency and ~1.5 Hz horizontal natural frequency. There are only two adjustments. The CT-2 is ideal for all types of benchtop microscopes.

This is the thinnest, most portable and most user-friendly isolator ever offered that is capable of delivering this performance.

**For International Orders, A Handling Fee of 5% is Added.
