Minus K vibration isolation
systems offer significant advantages for patch clamping, electrophysiology
measurements, fluorescent dye imaging, genomic sequencing and other
applications in biology and neuroscience. They eliminate the nuisance of air
and outperform air tables by a factor of 10 to 100, depending on the vibration
frequency. The bench top platforms are compact, saving valuable lab space, and
are easy to move around.

Vibration can be caused by a
multitude of factors that are internal and external to the building in which
the system resides, including vibrations from heating and ventilation system,
fans, pumps, and elevators as well as vibrations from adjacent road traffic,
nearby construction, loud noise from aircraft, and even wind and other weather
conditions that can cause movement of the structure. These internal and
external influences cause vibrations as low as 2 hertz (Hz) that can create
strong disturbances in sensitive equipment.

NEW CT-1 Ultra-Thin Low-Height
Tabletop Vibration Isolation Platform
 The
CT-1: This is the
thinnest, most portable and most user-friendly isolator ever offered that is
capable of delivering this performance.
The Compact Tabletop (CT-1)
uses Minus K's patented breakthrough technology allowing for the best
performance on the market in just a 2.25 inch tall isolation platform.more...
- Horizontal frequencies are
weight dependent.
- Horizontal frequency of
~2.25 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.

Vacuum Chamber Vibration
Isolation
Minus K
vibration isolation systems can be made vacuum compatible so they can be used
right inside vacuum chambers. In addition to their superior vibration
isolation performance, this offers other advantages of much lower payload
weights, more compact systems, and eliminates problems associated with vacuum
chamber feed-throughs. See below example with NASA/JPL SIM Interferometer
Testbed Spectral Calibration Development Unit (SCDU).
Our vibration
isolation systems have also been used to support entire vacuum chambers.
This offers the advantages of more standard designs and lower costs in some
cases. |

Isolation
Modifications for to the isolators based on your application
requirements could include:
• Use of Stainless Hardware
•
Removal of Paint and/or Powder Coating
• Removal of Anodizing
• Replacement of Nylon or Plastic Parts
• Electroless Nickel
on Steel Parts
• Venting Blind Holes
• Use of Vacuum Grease
for Low Outgassing
• Bare Aluminum
• We'll need to
provide custom
pricing for vacuum applications. The price is typically 3 times the standard
units for vacuum compatible (internal chamber) placement.

Nanoindentation & Micro Hardness
Testing
Vibration Isolation
Micro Hardness Testers and
Nano Indenters can be quite sensitive to vibrations that increase the noise
floor of critical measurements. The method of actually doing the measurements
varies by manufacturer, but the fundamental mechanical path is similar. In all
cases, the instruments need to be as still as possible to get the best
performance. Some of the instruments are most sensitive to the vertical axes
while others are more sensitive to the horizontal.
Minus K Technology
isolators are unique in that they can deliver 0.5 Hz performance both
vertically and horizontally. Most other isolators delivery their best
performance vertically (which is typically the most important axis to isolate)
and lower performance horizontally. While this is ok for some applications,
there are those, such as some micro hardness testers that are most sensitive
horizontally. For those instruments, our isolators offer by far the best
isolation available.
If you have no choice but to place on of these
instruments on the upper floor of a building, our isolators can make it
possible to get the best performance possible. We have provided isolation
solutions for many happy customers facing this very problem.
