K Technology currently builds
isolators to handle payloads from
3 lbs to 10,000 lbs (per isolator).
When you need the best isolation for your dollar.
patented technology will provide you true 1/2 Hz performance.
us your challenge.
This isolator has the same basic features of our all passive, negative-stiffness, manually-adjustable bench top isolators. It offers our very-low frequency isolation performance for payloads of many thousands of pounds.
The SM-1 negative-stiffness isolator is the basic building block of the FP-1 Floor Platform and other heavy multiple isolator systems. They require no air or electricity.
SM-1 isolator can be used alone or with any number of
additional units to achieve higher capacity systems. They
can be arranged in many geometrical configurations to
suit your application.
If there is a need, the isolators can be customized to achieve user specific needs. Eg., different horizontal and vertical frequencies, dampening, etc. They can also be made cleanroom and vacuum capatible.
The SM-1 isolators can also be placed on pedestals to increase the height of the isolation system.

Vibration Isolation Floor Platforms
Minus K's FP-1 Negative-Stiffness Vibration Isolation Platform Supports SEMs, TEMs and Large Metrology Systems
By Jim McMahon
Excerpted from Photonics Show Daily - January 2012
Specifically designed for SEMs (scanning electron microscopes), TEMs (transmission electron microscopes) and large metrology systems, the FP-1 Negative-Stiffness vibration isolation floor platform from Minus K Technology, Inc. enables low frequency vibration isolation for weight loads from 500 lbs. to over 12,000 lbs. The FP-1 can achieve natural frequencies of 0.5 Hz or less, vertical and horizontal.
isolators provide a unique and completely mechanical concept
in low-frequency vibration isolation for the field of large
load systems. In particular, the transmissibility - the
vibrations that transmit through the isolator - is substantially
improved over other systems, providing better isolation
performance without the need for air or electric power.
Also, substantial isolation can be provided for vibrations
as low as 1 and 2 Hz. Minus K has just announced the standardization
of their Negative-Stiffness SM-1 isolators, thus lowering
the cost of the FP-1 platforms making them more accessible
to universities and laboratories on tight budgets.
Minus K has had very good success with their FP-1 platforms and SM-1 isolators. One installation of a Negative-Stiffness FP-1 platform enabled a SEM on a badly vibrating second floor to go from 100,000 magnification to 500,000 magnification and revealed components of cotton fibers that could not be seen previously.
A national laboratory replaced its air isolators with Negative-Stiffness SM-1 isolators using its existing platform for an electron microscope. Researchers marveled over being able to get a high-resolution image and have it remain until the next day. With actual results like these being reported, Minus K has seen a dramatic increase in their SEM and TEM inquires.

With Minus K's standardization of the SM-1 large capacity isolators, the cost for a low frequency floor platform has been drastically reduced to less than one half the previous custom price.
For our international customers that are looking to save even more, the platform can be made locally with a design from Minus K purchased along with the necessary SM-1 isolators(this eliminates the shipping of the heavy platform).
