“Our company prefers the Minus K vibration isolation
platform for use with our SPM/NSOM system. This platform reduces
the noise to well below 0.1 nm which is unachievable with
any conventional optical table. The Minus K platform is particularly
effective in cutting low-frequency vibrations. Reducing the
noise by over an order of magnitude has helped us obtain optimal
SPM performance integrated with a variety of optical and electron
optical tools. This has led to new horizons in scanned probe
and integrated microscopy.”

“We have tested a Nano-K bench top platform for several
months; it has outperformed our air table in all specs. I
am very much impressed by its performance. As a designer in
the AFM field for over 15 years, I truly appreciate the ingenious
design of this bench top platform. It is simple and elegant.
It is the best for the buck for isolating an AFM system from
the floor vibrations.

“Vibration isolation is an absolute must for Atomic
Force Microscopy. The Nano-K isolators provide the best performance,
affordability and convenience available. They have enabled
us to get data in environments that would have been prohibitive
otherwise. Everyone involved in AFM should be using Nano-K
isolators.”

“We have found the last several years of working with
Minus K and your products very satisfying. Your tables are
honestly a great invention that actually live up to their
specs. With the Minus K we have been able to consistently
collect precision data that just wasn't possible with our
old air tables. Thanks for an awesome product.”

“We originally selected the Minus K vibration isolation
tables as a solution for challenging installations of our
nanomechanical test instruments, with the intention of sticking
with air tables as a lower cost, standard product. Within
a short period of time, we re-evaluated that decision and
began using Minus K tables on all of our Nano Indenter products.
The performance is exceptional ¯ since switching to Minus
K, field installation problems associated with vibration have
been virtually eliminated. But equally impressive are the
quality of the product, innovation in design, and outstanding
support. Minus K has been a great OEM partner!”

“We've used the Nano-K table and found its performance
to be significantly better than traditional air tables. With
the Nano-K, nanoindentation experiments on our NanoTest system
are now possible at very low depths (under 10 nm) without
worrying about the external environment.”

“We have used the Biscuit tables from Minus K and found
them to be far superior to tables we have previously tried.
We are especially impressed with the isolation performance
in the X-Y plane. Using these tables resulted in a ten fold
reduction in vibrational noise which greatly facilitated measurements
of absorption and fluorescence from neurobiological preparations.”

“My laboratory studies the brain activity using voltage-sensitive
dye imaging methods. Before the introduction of the Minus
K tables we used high quality air tables. These tables were
not adequate for isolating low frequency vibrations so we
had to put a second air table on top of the first one.
In 1995 we bought the first Minus K table. We were impressed
by its superb performance, at least ten times better than
the air tables we were using. We told this news to other scientists
and since then at least 20 laboratories have bought Minus
K tables. We have four of them in our laboratory. We all suffer
much less headaches from floor vibrations.”

“It is my great pleasure to provide this testimonial
for Minus K Technoloty vibration isolation systems. As a neuroscientist
depending extensively on electrophysiological and imaging
techniques, I am keenly aware of the fundamental importance
of properly isolating these rigs from building vibrations.
I have for many years relied on passive pneumatic vibration
isolation tables for this purpose. Recently, when moving labs,
I was confronted with a situation in which my existing vibration
isolation equipment was inadequate. Analysis of the building
and floor vibration characteristics revealed large amplitude
vibrations at frequencies below 5 Hz at this new location.
Field tests with an in vitro patch clamp rig, using a standard
pneumatic vibration isolation table were unsatisfactory. Attracted
by their performance claims (i.e., natural frequencies of
1/2 Hz or better) and competitive pricing I decided to test
a Minus K vibration isolation unit with the same in vitro
electrophysiology rig, despite my initial skepticism concerning
the manufacturer’s performance claims. The Minus K unit
performed magnificently, surpassing my best expectations.
We performed a number of tests. Perhaps the most vivid way
to illustrate the results of these tests is to say that a
gang of colleagues literally jumping around at no more than
8 ft distance did not cause any disturbance in an active patch
clamp recording. Based on these results, I am equipping my
lab with Minus K vibration isolation units. Summarizing, Minus
K solved my vibration problem in a very cost-effective manner
and I encourage my colleagues dealing with similar problems
to test these systems for themselves.”

“I just wanted to commend Minus K on building an
outstanding product – we are extremely pleased with
our BM-1 bench top isolator.
Minus K’s negative stiffness technology intrinsically
makes sense to me as a mechanical engineer, and brings truly
fresh thinking to the problems of vibration isolation.
Moreover, negative stiffness works – and not only does
it work, but it works better than many other solutions.
After we evaluated numerous audiophile and industrial vibration
isolation solutions, we found that Minus K was not only one
of the strongest performers for our high-end audio application,
but also provided excellent value.
Before learning of Minus K, we had anticipated needing
either an air based or active isolation solution to get the
sonic performance we wanted, and were pleasantly surprised
to find that we could achieve the same performance using a
passive solution from Minus K while simultaneously eliminating
the need and extra cost for special facilities like air or
power. In addition, installation and set-up couldn’t
have been quicker or easier – we unpacked our isolator
and had our application set up in about 20 minutes without
any difficulties.
You can count The Audio Archive as a satisfied customer,
and we will certainly look to Minus K again to meet our future
needs.”

"A Minus-k vibration isolation system should be considered
mandatory by anyone who is serious about vinyl playback. With
its 0.5-Hz natural frequency, the isolation performance of
the BM-8 system is vastly superior to most of the “audiophile”
products on the market. This upgrade to
my analog source has allowed me to hear everything that is
on the LP by thoroughly isolating the playback system from
ambient vibrations. We have done the “jump-up-and-down”
test many times: even heavy falling objects near the turntable
have absolutely no audible effect. I live in an 80-year-old
house built on a pier-and-beam foundation, about the furthest
thing from a well-damped oscillator. My listening room
therefore would be an extreme challenge for any vibration-isolation
system.
It is difficult to overstate the benefits of this level
of isolation to analog music reproduction. Images are
palpable and more stable, there’s an enormous reduction
in the “noise floor,” and it’s now possible
to appreciate the full scale and dynamic range of an LP recording. The
folks at Minus-k are extremely accessible and go out of their
way to make certain that their products work in your particular
application. In my case, I needed a modification so I
could independently level the isolator. They custom-engineered
a solution for me and shipped it within days.
I first became aware of their products as an atomic-force
microscope user, but decided to ignore the usual “do
not try this at home” caution. I am extremely glad
that I did and am considering another Minus-k system –
this time for laboratory use."
