Floor Platform with STACIS® 2100

TMC’s low-profile 65 Series Floor Platform Isolation Systems are designed for larger, floor-mounted instruments. These platforms effectively isolate instruments weighing a few hundred to tens of thousands of pounds and do so without the compromises in stability normally encountered when isolating instruments with a high center-of-mass.

Historically, we approached the problem of a tall, top-heavy payload by combining our Gimbal Piston™ Air Isolators with “ lifthoods” and a massive floor platform. This lowered the effective system center-of-mass and achieved the required stability.

Increasingly, our floor platforms are configured with our Stacis® Active Piezoelectric Isolators in place of our Gimbal Piston Isolators. The advantages of Stacis over pneumatic isolation include:

The Gimbal Piston Floor Platform is still available and recommended in many applications. We will help you determine whether a Stacis or Gimbal Piston Floor Platform is best for you.

TMC works closely with instrument manufacturers to ensure that our platform design meets the instrument’s footprint, structural, and utility requirements. We have successfully isolated hundreds of different instruments and are often already familiar with the tool requirements. In most instances, you need only provide the tool manufacturer and model for us to recommend a solution.

How to Order

  1. Identify the equipment or instrument model and configuration.
  2. Confirm the type of floor you have - conventional tiled lab floor, wooden beam and planks, etc.
  3. Tell us if the instrument manufacturer has made  a pre-installation site survey of the vibration level. In most cases a standard floor platform will be recommended. We may recommend taking our own site vibration measurements and look at the special conditions involved.
